Procedure

In a 2-liter flask, 30 g of p-(1,4,4-trimethyl-4-silacyclohexyloxy)styrene and 45 g of acetoxystyrene were dissolved in 560 ml of toluene. After thorough purging of oxygen from the system, 5.5 g of an initiator AIBN was added to the system, which was heated at 60° C. whereupon polymerization reaction took place for 24 hours. A similar subsequent procedure yielded a p-(1,4,4-trimethyl-4-silacyclohexyloxy)styrene/hydroxystyrene (3:7) copolymer. This polymer was transferred to a 3-liter flask where it was dissolved in 500 g of methanol and 400 g of acetone. 97 g of triethylamine and 50 g of pure water were added to the solution, which was heated at 60° C. whereupon hydrolysis reaction took place for 20 hours.
