1- and 2-Chloroanthracenes have been copolymerized with butadiene in the Mutual recipe and in the Mutual recipe with some added benzene. Using charging ratios of 90 parts of butadiene and 10 parts of chloroanthracene in the absence of benzene, the incorporation of the 1 isomer at 62% conversion is 16.9% and the incorporation of the 2 isomer at 80% conversion is 7.3%. In the presence of added benzene
