Procedure

A terpolymer of cyclopentadiene (CPD), isoprene, and isobutylene was prepared. This terpolymer had an Mv of 19,000 and an INOPO of 47. It contained 5.7 mole % CPD and 4.8 mole % isoprene by NMR analyses. 333 g. of this terpolymer was dissolved in 594 g. of hexane to yield 927 g. of a 36% cement and then converted to the hydroxyl derivative as follows:
