1. A method of preparing an acryloxy-functional organosilicon compound, said method comprising:
reacting (A) an initial organosilicon compound having one alcohol group and (B) an acrylate compound in the presence of (C) a catalyst having the formula M[RC(O)CHC(O)R]4, where M is a group IV transition metal and each R is an independently selected substituted or unsubstituted hydrocarbyl group, thereby preparing the acryloxy-functional organosilicon compound;
wherein the initial organosilicon compound (A) is mono-hydroxy functional and comprises a branched siloxy group.
