In this paper, a kind of water-soluble acrylic emulsion with methyl methacrylate (MMA) and butyl acrylate (BA) as hard and soft monomer respectively, acrylic acid (AA) and hydroxypropyl methacrylate as functional monomers, ammonium persulfate (APS) and ammonia as initiator and neutralizer respectively, was prepared by emulsion polymerization. The resulting emulsion possesses high solid content, low viscosity, high stability and film-forming properties, indicating that it would be applicable to water-based ink. The effect of the ratio of MMA to BA on the film-forming properties of resin and the influence of AA and HPA on the water-soluble property and viscosity of resin were investigated, and the relationship of reaction temperature and the emulsion stability was also studied. This paper can provides a certain reference to synthesis of acrylic resin and application of acrylic resin to the water-based ink.

This study adds nanopowder, such as ZnO and TiO2, in different concentrations to water-based woodenware coating, and explores the properties of the coating on the woodenwares. After the coating has been applied to the testing materials, the thickness and lightness are measured. These values are compared to the properties of the water-based woodenware coating with nanopowder of specific concentration, such as hardness, lightness and adhesion. According to the results of the experiments, adding TiO2 nanopowder to the AE-418 water-soluble polyurethane coating helps to increase the hardness of the coating. The amount added is positively related to the hardness of the coating; the result is the opposite with the WP-1715 water-soluble acrylic resin coating. After adding powder such as TiO2 or ZnO to the AE-418 water-soluble polyurethane coating, the lightness of the coating becomes lower. However, powder with higher concentration leads to higher lightness. In addition, the adhesion of the coating is stronger when nanopowder of higher concentration is added.

Hyperbranched polymer is a kind of non-linear polymers with highly branched structure and a lot of terminal groups. It has many advantages, such as high reactivity, good solubility and low viscosity. Hyperbranched polymer has become a focus in modern scientific domain. In this paper, polyester-type water-soluble hyperbranched monomer is prepared by the ring-opening polymerization reaction of maleic anhydride with polyol. Hyperbranched polyacrylate emulsion with 70-110nm was synthesized by emulsion polymerization using methyl methacrylate (MMA), butyl acrylate (BA), acrylic acid (AA) and hyperbranched polymer as comonomer. The effects of dosages and adding order of monomers, concentration of initator, type and amount of chain transfer agent on the polymerization are discussed. The as-prepared emusions were analyzed by FTIR, DSC, SEM. The solid content, particle size, stability of emulsion and morphology and water absorption of film were measured. The results showed that hyperbranched polyacrylate emulsion had low viscosity, high stability and can form very flat and smooth film. Hyperbranched polyacrylate emulsion can be widely applied in modern ink industry for its low cost,simple process and stable quality.

The Difference

Thermal and self-curing acrylic resins are frequently and versatilely used in dental medicine since they are biocompatible, have no flavor or odor, have satisfactory thermal qualities and polishing capacity, and are easy and fast. Thus, given their widespread use, their fracture resistance behavior is especially important. In this research work, we comparatively analyzed the fracture resistance capacity of thermo and self-curing acrylic resins in vitro. Materials and Methods: Five prosthesis bases were created for each of the following acrylic resins: Lucitone®, ProBase®, and Megacryl®, which were submitted to different forces through the use of the CS® Dental Testing Machine, usually mobilized in the context of fatigue tests. To this end, a point was defined in the center of the anterior edge of the aforementioned acrylic resin bases, for which the peak tended until a fracture occurred. Thermosetting resins were, on average, more resistant to fracture than self-curable resins, although the difference was not statistically significant. The thermosetting resins of the Lucitone® and Probase® brands demonstrated behavior that was more resistant to fracture than the self-curing homologues, although the difference was not statistically significant. Thermosetting resins tended to be, on average, more resistant to fracture and exhibited the maximum values for impact strength, compressive strength, tensile strength, hardness, and dimensional accuracy than self-curing resins, regardless of brand.

As the binder of waterborne inks, the capability of acrylic polymer has great influences on the quality of inks. In this contribution, structured latex particles with a poly (stryrene-butyl acrylate-methacrylate) core and a poly (butyl acrylate-methyl methacrylate-methacrylic acid-diacetone acrylamide (DAAM)) shell, which can be used as binders of water-based ink, were prepared by emulsion polymerization. The emulsion can cure in the course of film forming at ambient temperature through the reaction between DAAM and the adipic acid dihydrazide (ADH). Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), transmission electron microscopy (TEM), atomic force microscopy (AFM) were used to characterize the structures and study the properties of the latices. The drying time of the crosslinking latices was investigated. In addition, influences of DAAM monomer dosage and the mole ratio of DAAM to ADH on the mechanical properties of self-crosslinkable core-shell latices were also discussed. It was found that the core-shell crosslinkable particles with a low glass transition temperature (Tg) core and a high Tg shell have better film properties and would be more applicable to binders of water-based ink for plastic film, in comparison with those particles with a high Tg core and a low Tg shell.

Introduction: The daily use of orthodontic removable plates can interfere with the self-cleansing function of the mouth. Although various techniques have been proposed for cleaning removable orthodontic appliances, there is no consensus on the use of a safe method that preserves the physical properties of the appliance. This study aimed to investigate the effect of using hydrochloric acid (10%, for removal of mineral deposits) and sodium hypochlorite (5.25%, to remove organic matter and discolorations) on surface hardness and roughness of self-cure orthodontic acrylic resins. Materials & Methods: This cross-sectional laboratory study was conducted in the fall of 2017 at Isfahan University of Medical science and Isfahan University of Technology. In this study two orthodontic acrylic resins (Orthocryl® and Acropars®) were used. Eighty samples (12×10×3 mm) from each one were fabricated and divided into four groups (n = 20). Group 1: 15 minutes immersion in household cleaner liquid (Hydrochloric acid, 10%) followed by15 minutes immersion in household bleach liquid (Sodium Hypochlorite, 5.25%). In group 2, immersions were repeated just like group two times and in group 3, were done three times. Group 4 was as control and had no immersion. The surface hardness and roughness of samples were measured. Data were analyzed with Two Way ANOVA and the significance level was set at 0.05. Results: The number of immersion procedures did not significantly affect the surface hardness (p value = 0.958) and surface roughness (p value = 0.657) in the different study groups. There was no significant difference in the surface hardness between the two acrylic resin brands (p value = 0.077); however, Acropars acrylic resin samples exhibited significantly higher surface roughness compared to the Orthocryl acrylic resin samples(p value < 0.001). Conclusion: 15 minutes of immersion in 10% HCl, followed by 15 minutes of immersion in 5.25% NaOCl and repetition of the procedure three times did not significantly affect the surface hardness and roughness of self-cured acrylic resins.
