Synthesis and properties of allyl-terminated and silicon-containing polycarbonates

Polycarbonates containing reactive functional groups were synthesized with allylphenols as a molecular weight controller. The allyl-terminated polycarbonates and Si-H compounds were converted to new silicon-containing polycarbonates by hydrosilylation reaction with Rh catalyst. The silicon-containing polymers had lower glass transition temperatures than those of linear and allyl-terminated polycarbonates and had higher thermally oxidative stability.
