Abstract A series of terpolymers containing silyl pendant groups were prepared by free radical cross-linking copolymerization. Et 3 Si and HMe 2 Si were covalently linked with 4- vinylbenzyl and abbreviated as TESiMSt and DMSiMSt, respectively. Et 3 Si was covalently linked with 2-hydroxyethyl methacrylate (HEMA). The silyl-linked HEMA are abbreviated as TESiEMA. Free radical terpolymerization of the methacrylic acid (MAA) with different molar ...
