Reaction Conditions

Reaction Steps

A resin G-2b is prepared in a manner similar to that of preparing the resin C-2b, except that 36.0 g of α-methylstyrene and 84.0 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 −7° C. in the former. The resin G-2b thus obtained (an α-methylstyrene/4-tert-butyl-α-methylstyrene homopolymer) has yield: 80 g, softening point: 212° C., number-average molecular weight (Mn): 2784, and weight-average molecular weight (Mw): 10024.
