Zusammenfassung: | E 35551 "Liquid Prepolymer Compositions" A bitumen-free liquid prepolymer composition comprising : a) from 50 to 99% by weight of an isocyanate-containing prepolymer obtained by the reaction of a stoichiometric excess of diphenylmethane diisocyanate with an organic compound containing a plurality of isocyanate-reactive groups, and b) from 50 to 1% by weight of a substituted diphenylmethane compound which is free from ester groups, isocyanate groups and isocyanate-reactive groups and has a melting point below 25.degree.C, a boiling point above 150.degree.C and a fire point above 100.degree.C. The composition has a good stability and is useful for preparing elastomers and foams. |
