Abstract
A series of random copolymers of 4-vinylphenol with n-alkyl methacrylates were synthesized by free-radical copolymerization of 4-t-butyldimethylsilyloxystyrene and the corresponding alkyl methacrylates, followed by selective removal of the t-butyldimethylsilyl protective group. Copolymerizations were performed in benzene at 60°C using azobisisobutyronitrile as an initiator and reactivity ratios were determined using the Kelen-Tüdös method. Removal of the protective group was effected by tetrabutylammonium fluoride in tetrahydrofuran at ambient temperature. An infra-red spectroscopic characterization of these copolymers is reported.
