Abstract
Abstract Vinyltris(methoxyethoxy)silane (VTMES)was copolymerized with methyl methacrylate (MMA) and styrene (St) in bulk at 60°C using benzoyl peroxide as free radical initiator. The copolymer compositions were determined from elemental analysis, and reactivity ratios were calculated by the Kelen-Tuds graphical method. For MMA-VTMES, r1 = 11.2 ± 0.88 and r2 = 0 ± 0.16, and for St-VTMES, r1 = 11.2 ± 2.0 and r2 = 0 ± 0.34. In both systems r2 is near zero, indicating that VTMES undergoes little or no polymerization under the experimental conditions. The influence of the silicon comonomer on some of the basic properties of the copolymers (e.g., intrinsic viscosity, solubility, and thermal behavior) was studied.
