Abstract (en)
[origin: DE19738670A1] The invention relates to a prepolymer composition, especially for producing insulating foams based on a polyisocyanate with a functionality of >/=2 in addition to a polyol with a functionality of >/=2, wherein the prepolymer composition contains at least one catalyst which can catalyse formation of the prepolymer from the starting material and hardening of the prepolymer when used. The prepolymer contains oxazolidone groups resulting from the reaction of isocyanate groups with an epoxide, in addition to polyurethane groups from the reaction of the isocyanate groups with polyol and has an isocyanate content of 8-18 wt. %.
