Polymer Latex

Acrylic polymer latex has versatile role in many academic and industrial applications like paint, adhesives, textile, paper industry, concrete, surface coating, synthetic rubber and many ones. Acrylic base polymer latex can be prepared by various polymerization methods like Batch emulsion, Seeded emulsion, Situ miniemulsion, Atom transfer radical, Free radical copolymerization, Pickering miniemulsion, Semi-continuous seeded emulsion, dispersion copolymerization, aqueous suspension polymerization etc. in different solvents i.e. 1,1,2-trichloroethane, water, deionized water, 1,4-dioxane, chloroform, tetra hydro furan, toluene, benzene, nitric acid and so on. Acrylic latexes possessed various properties such as increased particle size which resist centrifugal nature and reduce viscosity of heavy oil, layered coating on steel improve lustre along with flexibility, tensile strength and thermal stability too. Acrylic latexes increase silicon intensity in silicon nanoparticles by controlling pH of emulsion during polymerization and also super paramagnetic behaviour of Fe2O3 nanocomposites latex controlled by pH. In this connection, many researchers have synthesized various acrylic base polymer latex or its composites, investigate its utility in different forms for different purposes to improve properties as required. In this review our main emphasis is to investigate the synthesis, characterisation and application of various acrylate polymer latexes.

Complete Concept

A company for the development of software for industrial applications "PBS" Belgrade has designed a modern information system for monitoring and controlling production in the paper industry, which is completely integrated with the technological equipment and production processes. The paper presents the complete concept of the system, from electronic communication with business partners over computer support to all the production processes in the factory, to the delivery of the products to the customers. Realized as a CIM (Computer Integrated Manufacturing) system, it enables management to have a complete overview of the condition of all the production and business activities, and ensures momentary and complete reliable information about all the parameters of the business system. Although the system was developed for the needs of the cardboard factory "Umka", with particular modifications, it could also be used in other factories of the paper and cardboard packaging industry.

The novel pseudo imprinted microspheres were synthesized by aqueous suspension polymerization using theophylline as the template and employed as a special sorbent of solid-phase extraction for selective extraction of acyclovir from swine tissue. The pseudo imprinted microspheres revealed high affinity and selectivity to acyclovir, and the matrix interferences could be efficiently eliminated, which make the extract of solid-phase extraction clean enough for HPLC analysis. The parameters that affect the extraction efficiency of solid-phase extraction were investigated, including solvent of extraction, volume of loading sample, washing and elution solvent, etc. Good linearity was obtained in a range of 0.05~15 μg/mL with correlation coefficient (r2) of 0.9991. The recoveries at three spiked levels were ranged from 91.4% to101.0% with RSD less than of 5.0%.

Background and Sources: Lipase enzyme is a naturally occurring enzyme found in the stomach and pancreatic juice. Its function is to digest fats and lipids, helping to maintain correct gallbladder function. Lipase is the one such widely used and versatile enzyme. These enzymes are obtained from animals, plants and as well as from several microorganisms and are sufficiently stable. These are considered as nature’s catalysts, but commercially, only microbial lipases are being used significantly. </P><P> Applications: They found enormous application in the industries of fat and oil processing, oleochemical industry, food industry, detergents, pulp and paper industry, detergents, environment management, tea processing, biosensors and cosmetics and perfumery. Various recent patents related to lipases have been revised in this review. </P><P> Conclusion: Lipases are very peculiar as they have the ability to hydrolyse fats into fatty acids and glycerols at the water-lipid interface and can reverse the reaction in non-aqueous media. This natural ability makes it the most widely used enzyme in various industrial applications. This article deals with the immense versatility of lipase enzymes along with the recent advancements done in the various fields related to their purification and mass production in industries.

Ultra High Molecular Weight

Acrylonitrile (AN) and itaconic acid (IA) were used to synthesize UHMWPAN by aqueous suspension method with 2,2’-azobisisobutyronitrile (AIBN) as the initiator and polyvinylalcohol (PVA) as the disperser at different temperatures (55°C~75°C) for different timings (1.0h~3.0h). The usage amounts of AN, IA, AIBN and PVA were also technical polymerization parameters used to obtain the optimal polymerization process. We found that the conversion and the viscosity average molecular weight both achieved the optimum levels when the conditions were as follows: the total monomer concentration (21wt%), the monomer ratio (AN: IA=98:2), the usage amount of the initiator (AIBN, 0.01wt%), the usage amount of the disperser (PVA, 0.1wt%), the polymerization temperature (70°C) and the polymerization time (2h).

AbstractWood processing residue, as an essential forest resource, is underestimated in the industrial applications. With the development of pulping technology, fiber quality and cost control have become the important prospects. It is very crucial to investigate the influencing factors of pulping, designed to reveal the relationship between fiber separation and physical performances. In this study, a range of effect factors of large-scale pulping process, including wood species, pretreatment, mechanical conditions, and post-bleaching treatment, were comprehensively investigated. The results illustrated that the industrial pulping process affected the dimensions of the fibers, their surface morphology, chemical structure, and thermal stability. The separated positions of the fibers were determined collectively by the mechanical temperature, time, and wood species. In addition, mild bleaching could effectively increase the crystallinity index, accessibility of the hydroxyl groups, and water retention values. However, it exerted a negative influence on the thermal stability. Further, chemical-assisted-refinement can replace higher temperature and prolonged ones to obtain pulp fibers with high quality while consuming less energy. Improved knowledge of how the industrial affects the fiber separation of a wood matrix and pulp quality is required as a basis for the development of the pulp and paper industry.
