Reaction Conditions

Reaction Steps

A resin P-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 60 to 63° C. The α-methylstyrene/indene copolymer resin thus obtained has yield: 70 g, softening point: 95° C., number-average molecular weight (Mn): 350, and weight-average molecular weight (Mw): 500.
