ResumoStyrene (monomer-1) has been copolymerized with [(2-methacryloyloxy)ethoxy]trimethylsilane, , at temperatures between 60 and 100° using benzoylperoxide as initiator. The compositions of the copolymers have been determined by silicon estimation; the reactivity ratios were calculated by the Fineman-Ross method. Arrhenius parameters have been derived. The difference between the activation energies, (E11–E12) favour self-propagation for the styrene radicals, whereas A11/A12 favours cross-propagation. In the case of silane radicals, (E22–E21) favours cross-propagation but A22/A21 favours self-propagation. The intrinsic viscosities and the thermal behaviours of the copolymers were also studied.
