  • Process for preparing graft polymers of .alpha.,.alpha.'-disubstituted-.beta.-propiolactones on isobutylene-triene-copolymers
    Patent number: 4282337
    Abstract: Graft-polymers of,.alpha.,.alpha.'-disubstituted .beta.-propiolactones on isobutylene-triene copolymers are prepared by reacting an isobutylene-triene copolymer with maleic anhydride and possibly with other functionalizing agents adapted to introduce acid and ester groups in the copolymer molecule and by neutralizing or hydrolyzing, or both, with a tetraalkylammonium base, said functional groups, said neutralization or hydrolysis, or both, being followed by a grafting reaction with pivalolactone.
