Reaction Conditions

Reaction Steps

A resin J-1 is prepared in a manner similar to that of preparing the resin I-1, except that 72 g of α-methylstyrene and 18 g of indene (that is, α-methylstyrene: 80 mass %, indene: 20 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 13 to 15° C. The α-methylstyrene/indene copolymer resin thus obtained has yield: 77 g, softening point: 145° C., number-average molecular weight (Mn): 800, and weight-average molecular weight (Mw): 2000.
