Procedure

The copolymerization of 1.2 g (12 mmoles) of maleic anhydride with 0.8 g. (12 mmoles) of cyclopentadiene using 0.3 ml. (1 mmole) of t-butyl peroxypivalate as catalyst at 80° C. was carried out in the presence of 1.8 ml. of chlorobenzene, using the procedure described in Example VI. The catalyst addition was carried out over a period of 10 min. and the reaction mixture was then maintained at 80° C. for an additional 50 min. The 1:2 cyclopentadiene-maleic anhydride copolymer was obtained in a yield of 0.64 g. (40%)
