Abstract

L'invention concerne l'industrie chimique. Elle a pour objet des compositions liquides de diisocyanatodiphénylméthane comprenant un diisocyanatodiphénylméthane dont 10 à 35 % des radicaux isocyanate ont été mis à réagir avec un mélange d'alkyléneglycols comprenant au moins trois glycols constitutifs dont chacun compte au moins 3 atomes de carbone, l'un des glycols étant le dipropylèneglycol, le tripropylèneglycol ou un polypropylèneglycol supérieur. Ces compositions sont préférées lorsqu'un long stockage doit précéder leur utilisation.
