Procedure

A copolymer of 2-vinyl pyridine and para-aminostyrene was prepared in a similar manner to example A with the exception that toluene was used instead of ethanol and only 2.80 ml of para-aminostyrene was used. The resultant product was purified by allowing the toluene to evaporate, redissolving the precipitate in dioxin and reprecipitating with water. The resultant polymer had a number average molecular weight of about 21,500 and a weight average molecular weight of about 54,000 as determined by GPC.
