Acrylate-functional branched organosilicon compound, method of preparing same, and copolymer formed therewith

A method of preparing an acrylate-functional branched organosilicon compound, said method comprising reacting (A) a branched organosilicon compound having one halogen-functional moiety and (B) an acrylate compound in the presence of (C) a catalyst to give the acrylate-functional branched organosilicon compound;

• wherein the branched organosilicon compound (A) has one of the following general formulas:
• where X comprises the halogen-functional moiety;
• and each 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;
• where each R6 is selected from R and —[OSiR2]mOSiR3;
• where each R is an independently selected substituted or unsubstituted hydrocarbyl group;
• where 0≤m≤100;
• with the proviso that at least one of R4, R5 and R6 is —[OSiR2]mOSiR3;
• and where at least one of R4 is —[OSiR2]mOSiR3;
• or
• where each R, R5, and X are independently selected and defined above;
• or
• where each R, R5, and X are independently selected and defined above;
• and
• wherein the catalyst (C) comprises an iodide compound.
