Abstract:
The present invention relates to the use of a compound of formula (I): wherein: —R represents —OH or —NH2; —A1 represents a divalent alkylene radical, straight or branched, having from 2 to 20 carbon atoms; —A2 represents a divalent alkylene radical, straight or branched, having from 1 to 20 carbon atoms; —X1 and X2 represent, independently of each other, —NH— or —O—; —A3 represents a divalent alkylene radical, straight or branched, having from 1 to 10 carbon atoms; —Z represents a hydrogen or a group of formula (A′): wherein A1, A3 and R are as defined above in formula (I), for the preparation of a polymer chosen among polyurethane, polyester and polyamide.
