Adhesive compositions based on ethylene-unsaturated acid ester copolymers and containing hydroxyl functional groups

摘要

The present invention relates to crosslinkable hot-melt adhesive compositions in the form of prepolymer containing free isocyanate functional groups; the said prepolymer results from the reaction of a polyisocyanate and of a copolymer (A) of ethylene and of at least one unsaturated carboxylic acid ester and containing hydroxyl functional groups. These adhesives are crosslinked by the ambient moisture.
