Reaction Conditions

Reaction Steps

A resin M-1 is prepared in a manner similar to that of preparing the resin I-1, except that 54 g of α-methylstyrene and 36 g of indene (that is, α-methylstyrene: 60 mass %, indene: 40 mass %) are used and that the addition of the catalyst is carried for 15 minutes and the polymerization reaction is allowed to proceed for 1 hour in a state where the temperature of the reaction mixed solution is maintained in the range of 10 to 15° C. The α-methylstyrene/indene copolymer resin thus obtained has yield: 86 g, softening point: 165° C., number-average molecular weight (Mn): 1000, and weight-average molecular weight (Mw): 3000.
