POLYURETHANE CONTAINING ACRYLOYL OR METHACRYLOYL GROUP

Polyurethanes which contain (meth)acryloyl groups, are peroxidically crosslinkable in the presence of atmospheric oxygen and have been prepared by reacting a) a polyisocyanate component, b) an alcohol component containing (meth)acryloyl groups, c) at least one beta , gamma -ethylenically unsaturated...

Beschreibung
Zusammenfassung:	Polyurethanes which contain (meth)acryloyl groups, are peroxidically crosslinkable in the presence of atmospheric oxygen and have been prepared by reacting a) a polyisocyanate component, b) an alcohol component containing (meth)acryloyl groups, c) at least one beta , gamma -ethylenically unsaturated ether alcohol and d) at least one polyhydric alcohol while observing an NCO:OH equivalent ratio of 0.5:1 to 1:1, a process for the preparation of the polyurethanes by reacting said starting materials, and the use of the polyurethanes for the production of mouldings, including cured putties, trowelling fillers or surface coatings (paints).
