Abstract

Polyurethane vinyl ethers are obtainable by reacting PA1 A) 1 NCO equivalent of one or more isocyanurate-containing polyisocyanates with PA1 B) 0.01-1.0 OH equivalent of one or more monohydroxyvinyl ethers and PA1 C) 0-0.99 equivalent of functional groups of further compounds, which groups are reactive with OCN.
