The present invention pertains to low emission polyurethane polymer products based on autocatalytic polyols made by modification of conventional polyols with tertiary amines and processes for their manufacture. The tertiary amine is bound to a conventional polyol by means of an epoxide, epichlorohydrin, or grafting by means of an azo and/or peroxide initiator or sulfonyl azide.
L'invention concerne des produits polymères en polyuréthanne à faible émission, à base de polyols autocatalytiques, fabriqués par modification de polyols classiques au moyen d'amines tertiaires, ainsi que des procédés de fabrication desdits produits. Selon l'invention, l'amine tertiaire est liée à un polyol classique au moyen d'un époxyde, d'une épichlorohydrine, ou greffée au moyen d'un initiateur azo et/ou peroxyde ou d'un azide sulfonyle.
