Procedure

The same procedure as in Preparation Example 1 was repeated except that 250 ml of styrene was replaced with 225 ml of styrene and 25 ml of p-methylstyrene, thereby obtaining 104 g of a syndiotactic p-methylstyrene-styrene copolymer (the content of p-methylstyrene=7 mol). The weight-average molecular weight of this copolymer was 370,000.
