A method of preparing an acrylate-functional branched organosilicon compound (“compound”) is provided, and comprises reacting (A) a branched organosilicon compound and (B) an acrylate compound in the presence of (C) a catalyst, wherein component (A) has the general formula X—Si(R 1 ) 3 , where X comprises a halogen-functional moiety and each R 1 is selected from R and —OSi(R 4 ) 3 , with the proviso that at least one R 1 is —OSi(R 4 ) 3 ; each R 4 is selected from R, —OSi(R 5 ) 3 , and —[OSiR 2 ] m OSiR 3 ; each R 5 is selected from R, —OSi(R 6 ) 3 , and —[OSiR 2 ] m OSiR 3 ; each R 6 is selected from R and —[OSiR 2 ] m OSiR 3 ; each R is an independently selected hydrocarbyl group; and 0≤m≤100; with the proviso that at least one of R 4 , R 5 and R 6 is —[OSiR 2 ] m OSiR 3 . The compound prepared by the method, a copolymer comprising the reaction product of the compound and a second compound, a method of forming the copolymer, and a composition comprising the copolymer are each also provided. |
