Isobutylene → N-(4-ethylphenyl)maleimide isobutene

Participants

Reaction Steps

In a one-liter autoclave were charged 400 ml of toluene as a polymerization solvent, 0.001 moles of perbutyl neodecanoate as a polymerization initiator, 0.42 moles of N-(4-ethylphenyl)maleimide, and 4.05 moles of isobutene, and the mixture was subjected to polymerization reaction under a polymerization condition at a polymerization temperature of 60° C. for a polymerization time of 5 hours, to obtain N-(4-ethylphenyl)maleimide-isobutene alternating copolymer. The thus obtained N-(4-ethylphenyl)maleimide-isobutene alternating copolymer had a weight average molecular weight (Mw) (as reduced into standard polystyrene) of 155,000 and an Mw/Mn of 2.6.
