Linear crosslinkable polyurethane obtained from monomers comprising a) at least one diisocyanate having from 2 to 30 carbon atoms, b) at least one aliphatic or cycloaliphatic diol having from 2 to 30 carbon atoms, whose carbon chain is covalently bonded to at least one carboxyl group, and some or all of said carboxyl groups have been esterified with an olefinically unsaturated C3-C8 alcohol or with the glycidyl ester of an olefinically unsaturated C3-8 carboxylic acid; and the polyurethane containing additionally radicals of at least one aliphatic, cycloaliphatic or cycloaliphatic-aliphatic diol, of at least one oligomeric or polymeric oxa-alkylene glycol, of a polyether diol, polycarbonate diol, polylactonadiol or a diol based on polybutadiene or polyisoprene. |
