Alkenyl Ether Polyols

Abstract

The invention relates to a method for producing radiation-curable alkenyl ether polyols, to radiation-curable alkenyl ether polyols produced using the method according to the invention, and to the use thereof for the synthesis of radiation-interlinkable oligomers or polymers by means of polyaddition reactions or polycondensation reactions, in particular for the synthesis of radiation-curable polyesters, polyethers, polyurethanes and polyureas, particularly preferably UV-curable polyurethanes. The invention also relates to radiation-curable polyurethane polymers that are obtained by reacting at least one alkenyl ether polyol according to the invention with a polyisocyanate.
