Abstract

A process for the preparation of an adhesive for weakly unsaturated rubbery polymers, comprising: a) reacting in an organic solvent, a polylactone terminated by hydroxyl and a diisocyanate in a molar ratio of 1: 1.00 to 1: 1.20 ; b) reacting a hydroxyl-terminated polylactone graft polymer, which has been obtained by grafting a lactone or a mixture of lactones in a rubbery polymer containing hydroxyl groups, with a diisocyanate in an amount just sufficient to convert all of them into an organic solvent. The terminal hydroxyl groups in diisocyanate residues containing a free isocyanate group c) react in an organic solvent, either separately or in combination with reaction b) a branched polylactone containing 3 to 4 hydroxyl groups with a diisocyanate in a just enough amount to convert all terminal hydroxyl groups to diisocyanate residues containing a free isocyanate group, and d) combine the solutions obtained according to reactions a), b) and c).
