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. It is a copolymer emulsion of organosilicone and acrylate. The backside temperature of the coating was kept at 150 C after the 120 min fire test.
The synergistic effects of EG and palygorskite apparently promoted the flame retardant and heat insulation performance. 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. Silicon-acrylic emulsion is a kind of composite emulsion. Silicone-acrylic emulsion was used to prepare intumescent fire retardant coating. 1-(1-propenyl) sulfosuccinate (M-10S) as.

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. ACR-SIL dispersions were obtained by emulsion polymerization of mixtures of the same silicone monomers in aqueous dispersions of acrylic/styrene copolymers. Key Words: Silicone-acrylate emulsion, Emulsifier-free polymerization, Nano-sized particle, Antifouling coating. The acrylate-silicone emulsions were prepared by emulsion copolymerization of methylmethacrylate (MMA), butylacrylate (BA), methacrylic acid (MAA) with.
