Patent

CA 2392045

Polyurethane prepolymers having a reduced amount of unreacted monomeric diisocyanate, particularly diphenyl-methane dissocyanate (MDI), prepared by distilling the prepolymer reaction product in the presence of a least one inert solvent whose boiling point is slightly below that of the monomeric diisocyanate; and to high performance cast polyurethane elastomers from the thus obtained prepolymers using diamine and/or diol chain extenders.

L'invention concerne des prépolymères de polyuréthanne ayant un taux réduit de diisocyanate monomère inaltéré, notamment du diphénylméthane diisocyanate (MDI), préparé par distillation du produit de réaction prépolymère en présence d'au moins un solvant inerte dont le point d'ébullition se situe légèrement au-dessous du point d'ébullition du diisocyanate monomère. L'invention concerne également des élastomères de polyuréthanne coulé haute performance issus des prepolymères ainsi obtenus au moyen d'allongeurs de chaîne diamine et/ou diol.
