実験手順

A solution of 13.9 g. 4-chlorostyrene and 10.4 g. styrene in 120 ml. dry benzene containing 0.24 g. azobisisobutyronitrile (Vazo® 64, du Pont) was stirred under nitrogen at 58°-64° C. for 24 hours. The solution was solvent stripped to a colorless syrupy residue which was dissolved in 50 ml. benzene and the solution added slowly with stirring to 300 ml. absolute ethanol. The precipitated polymer was filtered, washed with ethanol, and dried. The yield was 15.2 g. Analysis of the polymer showed presence of 15.83% chlorine, equivalent to a copolymer containing 47 mole % styrene and 53 mole % 4-chlorostyrene units in the repeat unit.
