Procedure

A solution of 0.3 ml. of t-butyl hydroperoxide-70 in 6.6 g. of cyclopentadiene was added in 4 portions over 10 min. to 9.8 g. of maleic anhydride at 205° C. After a subsequent 15 min. heating period at 205° C., the 1:2 cyclopentadiene-maleic anhydride copolymer was obtained in a yield of 4.5 g. (34%). When the additional heating period was increased from 15 min. to 80 min. at 205° C., the yield was increased to 5.0 g. (38%). The copolymer had a softening point of 280° C.
