Patent ID: 8377634

Claim:
A method of preparing an acrylic functional resin comprising co-hydrolysis and subsequent condensation of (I) a trialkoxysilane having the formula R 2 Si(OR 3 ) 3 ; where R 2 is selected from a linear or branched alkyl, aryl or alkenyl group having 1 to 8 carbon atoms and R 3 is an alkyl group having 1 to 3 carbon atoms, with (II) an acryloxy functional trialkoxysilane having the formula (CH 2 ═CR 1 COOR)Si(OR 3 ) 3 where R 1 is hydrogen or methyl group, R is a hydrocarbylene group having 1 to 8 carbon atoms and R 3 is an alkyl group having 1 to 3 carbon atoms, in the presence of base catalyst, wherein the co-hydrolysis is carried out in the presence of base catalyst.
