Branched organosilicon compound, method of preparing same, and copolymer formed therewith

Abstract

A branched organosilicon compound (“compound”) is provided having the general formula: (R1)3Si—X—NR2R3, where X is a divalent linking group; R2 is H or R; R3 comprises an acryloxy moiety; each R1 is selected from R and —OSi(R4)3, with the proviso that at least one R1 is —OSi(R4)3; where each R4 is selected from R, —OSi(R5)3, and —[OSiR2]mOSiR3; where each R5 is selected from R, —OSi(R6)3, and —[OSiR2]mOSiR3; and where each R6 is selected from R and —[OSiR2]mOSiR3, with the proviso that at least one of R4, R5 and R6 is —[OSiR2]mOSiR3; 0≤m≤100; and each R is a substituted or unsubstituted hydrocarbyl group. Also provided is a method of preparing the compound, a copolymer comprising the reaction product of the compound and a second compound reactive with the compound, a method of forming the copolymer, and a composition including at least one of the compound and the copolymer.
