Abstract
AbstractStyrene was copolymerized with [(2‐methacryloyloxy)propoxy]‐trimethylsilane (2‐MAPTMS), [(2‐methacryloyloxy)propoxy]‐dimethylphenylsilane (2‐MAPDMPS), and [(2‐methacryloyloxy)‐propoxy]‐diphenylmethyl silane (2‐MAPDPMS) in toluene at temperatures between 60 and 90°C using azobisisobutyronitrile (AIBN) as initiator. The compositions of the copolymers were determined by silicon estimation. The reactivity ratios were calculated by the Kelen–Tüdös method. The reactivity ratio r1 (styrene) is higher for styrene‐2‐MAPDPMS than for the styrene‐2‐MAPDMPS and styrene‐2‐MAPTMS copolymerzation system. The difference between the activation energies E11 – E12 favors self‐propagation of the polystyryl radical, whereas the ratio of preexponential factors A11/A12 favors cross propagation. For the 2‐MAPTMS radical, the difference E22 – E21 favors cross propagation but the ratio A22/A21 favors self‐addition. The intrinsic viscosities and the theramal behavior of the copolymers were also studied.
