Increasing Temperature

A waterborne polyurethane-based polymeric dye (WPU-CFBB) was synthesized by anchoring 1, 4-bis(methylamino)anthraquinone (CFBB) to waterborne polyurethane chains. The number molecular weight, glass transition temperature, and average emulsion particle size for the polymeric dye were determined, respectively. This polymeric dye exhibited intriguing optical behaviors. The polymeric dye engendered two new absorption bands centered at about 520 nm and 760 nm if compared with CFBB in UV-vis spectra. The 760 nm peak showed hypsochromic shift with the decrease of average particle sizes. The polymeric dye dramatically demonstrated both hypsochromic and bathochromic effects with increasing temperature. The fluorescence intensity of the polymeric dye was much higher than that of CFBB. It was found that the fluorescence intensities would be enhanced from 20°C to 40°C and then decline from 40°C to 90°C. The fluorescence of the polymeric dye emulsion was very stable and was not sensitive to quenchers.

Slight Rise

Unanesthetized dogs were given either 3.0 g fat/kg as a 20% fat emulsion or heparin (2 mg/kg) intravenously or both. Plasma free fatty acids (FFA) and lipolytic activity were determined at intervals. In some experiments hexamethonium (5 mg/kg), a sympathetic ganglionic blocking agent, was administered intravenously either before or after fat or heparin. In fasting dogs fat infusion produced a moderate and heparin caused a slight rise in plasma FFA. Heparin given during lipemia produced a marked elevation of plasma FFA. The plasma lipolytic activity was increased after fat emulsion or heparin. Hexamethonium reduced the fasting plasma FFA about 70% or 0.40–0.6 mEq/liter. A similar reduction of plasma FFA also was observed when hexamethonium was administered during fat infusion or after heparin. Hexamethonium did not affect the increase in plasma lipolytic activity following the administration of fat emulsion or heparin. It seems probable that the increase in plasma FFA observed after intravenous infusion of fat emulsion or heparin is mainly due to the result of intravascular lipolysis.

Hydrophilic Polyurethane

Several cationic water-based polyurethanes end-capped with silicone coupling agent with different ion abundance are prepared. The effects of ion abundance of those polyurethanes on its emulsion particle size distribution, wet rubbing fastness improvement, hydrophility and soft handle are studied. The results show that the sample with moderate cationic ion abundance has optimal efficiency for color fixing of reactive dyes, and the quaterized cationic groups in polyurethane molecule should has positive contribution to hydrophility and soft handle of the treated fabric, especially for the color fabric treated with higher concentration polyurethane emulsion.

Different Content

Under the action of initiator(BPO), the α-methyl acrylic acid (α-MAA), butyl hexafluorobutyl methacrylate (HFMA) and other monomers are graft copolymerized into epoxy molecular. By adding N, N-dimethyl ethanolamine, fluorine-containing water-based epoxy resin emulsion can be prepared. By orthogonal experiments, the amount of acrylic monomer, BPO dosage, grafting temperature and other optimum conditions can be determined. Infrared spectroscopy (FT-IR) characterization confirms acrylic monomers successfully grafted to the epoxy resin molecules. The study focuses on the effect of different content of HFMA on modified emulsion particle size and contact angle of coating. The results shows that the introduction of HFMA monomer made the smallest average particle size of emulsion low to 165 nm, and the contact angle against water is increased by 20°. After determining the conventional and environmental performance of the emulsion, the results shows that this preparation of epoxy resin emulsion can fully meet the requirements of waterborne coatings.
