Abstract (en)

[origin: EP0299462A2] This invention relates to a liquid prepolymer composition which contains free isocyanate groups and which is the reaction product of a stoichiometric excess of a polyisocyanate and an active hydrogen-containing compound which contains an internal rigid polyaromatic grouping. This invention also relates to polyurethane and/or polyurea polymers made from these prepolymer compositions.
