Abstract

Based on experimental studies, a method for obtaining a powdered silicone-acrylic polymer by emulsion copolymerization of acrylic acid and 3-methacryloxypropyl-trimethoxysilane using a reaction initiator (ammonium persulfate) for implementing the modifications in the polymer cross-link to impart improved physicochemical properties to the final product was presented in the paper.

The optimum conditions of synthesis were determined. Based on the study of the kinetics of the copolymerization reaction by the graviometric method, it was found that it is advisable to conduct the reaction for 4.5 hours at a temperature of 90 oC, since the copolymer yield after this time was 45.3 %.

During the synthesis, silicone-acrylic polymer, which is a white powder without strong smell, insoluble in organic solvents was obtained. The copolymer was characterized using IR spectrum analysis and dispersion determination.

The obtained silicone-acrylic copolymer is recommended for use in paints and varnishes as a surface modifier.
