Title:
N置換ピロールにより失活させたリビング及び準リビングカチオン性テレキーリック高分子およびその製造方法
Document Type and Number:
Japanese Patent JP5039272
Kind Code:
B2
Abstract:
Disclosed is a method of preparing terminally functionalized telechelic polymers using a cationic living polymer product or a terminal tert-chloride chain end of a carbocationic quasiliving polymer product, which comprises quenching the polymer product with an N-substituted pyrrole to thereby functionalize the N-substituted pyrrole at the terminal reactive polymer chain end(s). Also disclosed are the terminal functionalized polyisobuyl N-substituted pyrrole compounds where the polyisobutyl group is substituted at the 2 and 3 position of the N-substituted pyrrole.
