Abstract
Novel crosslinkable hot-melt adhesive compositions, curable by atmospheric moisture, include (i) the prepolymerizate of an hydroxylated ethylene/vinyl acetate copolymer with a stoichiometric excess of a polyisocyanate, e.g., a diisocyanate, such prepolymerizate containing an effective crosslinkable amount of free isocyanate functional groups, and, optionally, (ii) an adhesive tackifying resin.
