Procedure

By using the same autoclave as used in Preparation Example 1, 300 g of p-tert-butylstyrene polymer (Mw=20.4×104, Mn=11.2×104, Mw/Mn=1.82) prepared by suspension polymerization in water, was charged instead of 300 g of polystyrene in Preparation Example 1. The hydrogenation reaction and post-treatment were conducted in the same manner as in Preparation Example 1 except that the hydrogenation conditions were changed as identified in Table 1, whereby polyvinyl p-tert-butylcyclohexane was obtained.
