The invention relates to NCO-functional prepolymers prepared from dicyclohexylmethane diisocyanate (H12MDI hereinafter) and polyether polyols, with a reduced tendency to crystallization, a fraction of the H12MDI being blended with further monomeric isophorone diisocyanate (IPDI hereinafter), so making it possible to reduce or prevent entirely the tendency to crystallization, and also to the preparation and use.
L'invention se rapporte à des prépolymères à fonctions NCO à base de diisocyanate de dicyclohexylméthane (appelés H12MDI par la suite) et de polyéther-polyols ayant une tendance limitée à la cristallisation, le H12MDI étant mélangé partiellement avec un autre diisocyanate d'isophorone monomère (appelé IPDI par la suite), permettant ainsi de réduire voire d'inhiber totalement la tendance à la cristallisation. L'invention se rapporte également à leur préparation et à leur utilisation.
