Li, Rui-Qi; Huang, Tao; Gong, Shu-Ling published the artcile< Preparation of high hydroxyl self-emulsifying polyester and compounding with acrylate>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is hydroxyl polyester acrylate emulsion film waterborne coating.
Waterborne saturated polyester (WSP) with high hydroxyl content was prepared through solution polymerization by using stepwise feeding and stage heating methods. The stability of polyester dispersion was enhanced via control of the mol. structure and polymerization process. The effect of polymerization conditions, monomer types, and catalyst types was determined The effects of the alc.-to-acid ratio, trimethylolpropane content, the feeding method, the content of terminal monomer and branching monomer on the dispersion were investigated. The stability of the self-emulsifying polyester and water resistance of the film were excellent. The transesterification of WSP afforded waterborne unsaturated polyester. Polyester-acrylate composite emulsion was prepared by phys. blending or copolymerization with unsaturated polyester. The viscosity of the composite emulsion, hardness and water resistance were improved. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 48278.
