PROCESS FOR THE PREPARATION ACRYLIC PAINT

摘要

The thermosetting silicone acrylic paint is prepd. by addition and polycondensation reaction of the reactive acryl oligomeric copolymer (A) of a acrylic cpd. of formula (I) and a aorylic cpd. of formula (II) contg. hydroxy gp., with the organic Si lane cpd. of formula (III) contg. vinyl gp. which alcoxy equivalent is 1/0.8-1/1.2 w.r.t. the cpd. (A), to owtain a silicone acryl copolymer; then preparing the copolymer to the paint. In the formulas, R1,R3,R5 are H or CH3; R2,R4 are H or opt. substd. monovalent aliphatic hydrocarbon; R6,R7 and R8 are C1-4 alcoxy or C1-8 aliphatic hydrocarbon; n=1-6.
