Procedure

Into a 1-liter autoclave were introduced 400 mL of toluene as a polymerization solvent, 0.001 mol of perbutyl neodecanoate as a polymerization initiator, 0.42 mol of N-(2,6-diethylphenyl)maleimide, and 4.05 mol, of isobutene. A polymerization reaction was conducted at a polymerization temperature of 60° C. for a polymerization time of 5 hours to obtain an N-(2,6-diethylphenyl)maleimide-isobutene alternating copolymer. The N-(2,6-diethylphenyl)maleimide-isobutene alternating copolymer obtained had a number-average molecular weight of 65,000.
