SYNTHESIS AND CHARACTERIZATION OF SILYLATED POLYSTYRENES

Poly(p-trimethylsiloxystyrene) (1a), poly[p-(tert-butyldimethylsiloxy)styrene] (1b), poly[p-(trimethylsiloxy)-a-methylstyrene] (1c), poly[p-(tert-butyldimethylsiloxy)-a-methylstyrene) (1d) and poly{p-[2-(tert-butyldimethylsiloxy)ethyl]styrene} (1e) were prepared by free-radical or cationic polymerization of the corresponding monomers. Poly{[p-[2(trimethylsiloxy)ethyl]styrene]-co-[p-(2-hydroxyethyl)styrene]} (2a) was synthetized by anionic polymerization of the corresponding trimethylsilylated monomer, followed by acid hydrolysis of the resulting polymer. Poly{[p-[2-(trimethylsiloxy)ethyl]styrene]-co-[p-(tert-butoxycarbonyloxy)styrene]} (2b) were prepared by free-radical polymerization of the corresponding monomers.
