実験手順

t-butyl methacrylate and trimethylsilylmethyl acrylate were mixed at a mixing ratio of 1:1 so as to form a toluene solution having a monomer concentration of 5 mol/liter. Next, 2 mol %, on the basis of the monomer, of AIBN was added to the mixture, and the mixture was retained in an oil bath at 80° C. for 3 hours with stirring. Thereafter, the mixture was left standing at room temperature to cool, and the reaction product was diluted with toluene. The toluene solution was dropped into large quantities of a mixed solvent of methanol and water having a mixing ratio of 1:1, and the resulting precipitate was filtered and dried to obtain a trimethylsilylmethyl acrylate/t-butyl methacrylate copolymer represented by the following formula, at a yield of 85%. The molecular weight was 23,000 and the dispersion was 1.63. ##STR17## wherein each of m and n is a positive integer.
