Reaction Conditions

Reaction Steps

51.0 g of the same p-vinylphenol fraction as used in Example 1, obtained by vacuum flash distillation was placed in a 300-ml flask together with 51.0 g of acetone. To the resulting mixture being stirred and cooled to 0° C. was dropwise added 1.0 ml of an acetonitrile solution containing 0.02 g of iodine. A polymerization reaction was conducted for 1 hour at 0° C. to obtain 8.3 g of a poly(p-vinylphenol). The polymer had a Mw of 13,800, a Mn of 11,200, a light transmittance at 248 nm, of 76.3% and a light transmittance at 450 nm, of 95.0%.
