Procedure: In one typical embodiment, the polymer can be synthesized by dissolving an acetoxystyrene monomer, a tertiary alkyl (meth)acrylate monomer and an indene monomer in an organic solvent, adding a radical initiator thereto, heat polymerizing the monomers, and subjecting the resulting polymer to alkaline hydrolysis in an organic solvent for deblocking the acetoxy group, thereby forming a ternary copolymer of hydroxystyrene, tertiary alkyl (meth)acrylate and indene. Examples of the organic solvent used in polymerization include toluene, benzene, tetrahydrofuran, diethyl ether, and dioxane. Representative of the polymerization initiator are 2,2′-azobisisobutyronitrile, 2,2′-azobis(2,4-dimethylvaleronitrile), dimethyl-2,2-azobis(2-methylpropionate), benzoyl peroxide and lauroyl peroxide. Polymerization may be effected by heating at about 50 to 80° C. The reaction time is usually about 2 to 100 hours, preferably about 5 to 20 hours. The base used in the alkaline hydrolysis is selected from aqueous ammonia and triethylamine, to name a few. The reaction temperature is about −20° C. to 100° C., preferably about 0 to 60° C. The reaction time is usually about 0.2 to 100 hours, preferably about 0.5 to 20 hours. In one typical embodiment, the polymer can be synthesized heat polymerizing the monomers hydrolysis in an organic solvent

Procedure: A 22 L reactor was charged with 2.919 kg acetoxystyrene, 1.538 kg t-butyl acrylate, 231 g BPO and 6 L toluene. The reactor was purged with nitrogen, and the reaction solution was heated at 60° C. under a N2 atmosphere for 23 h. The solution was then cooled to room temperature, diluted with an additional 12 L of toluene, and 248 L of heptane:isopropyl alcohol (30:1) was added. The precipitate was collected by vacuum filtration, and washed with 24 L heptane. The solid was recrystalized by first dissolving it in 15 L acetone and then adding 300 L isopropyl alcohol:water (51:24 v/v). The product was collected by vacuum filtration, rinsed with 30 L 1:1 isoproyl alcohol:water, and then dried at 50-55° C. under vacuum to a constant weight.

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.
