PREPOLYMER COMPOSITION LOW IN MONOMERS, MADE OF UNSYMMETRICAL POLYISOCYANATES AND STERICALLY HINDERED POLYOLS

摘要

A prepolymer composition, particularly for the production of polyurethane foams, based on polyisocyanates and polyols, wherein the prepolymer composition contains PU prepolymers from the reaction of asymmetrical polyisocyanates, comprising at least two isocyanate groups, with sterically hindered polyols having at least two hydroxy functions.
