Procedure

A resin I-2b is prepared in a manner similar to that of preparing the resin C-2b, except that 12.0 g of α-methylstyrene and 108.0 g of 4-tert-butyl-α-methylstyrene are used and that the polymerization reaction is allowed to proceed in a state where the temperature of the reaction mixed solution is maintained in the range of −8 to −6° C. in the former. The resin I-2b thus obtained (an α-methylstyrene/4-tert-butyl-α-methylstyrene homopolymer) has yield: 76 g, softening point: 215° C., number-average molecular weight (Mn): 2674, and weight-average molecular weight (Mw): 10695.
