Abstract

L'invention décrit l'obtention et une application de certains copolymères greffés. On polymérise un ou des monomères à insaturation éthylénique en présence d'un azo-diester-polyol. Le groupe azoïque du polyol sert de site de formation de radicaux libres pour l'amorçage de la réaction de copolymérisation par greffage. Les copolymères peuvent notamment servir à formuler des compositions de production de mousses de polyuréthannes très souples.
