Elastomeric, ethylenically unsaturated polyurethanes and radiation polymerizable mixtures containing such polyurethanes |
摘要 |
A polyurethane corresponding to the formula: <IMAGE> (I) <IMAGE> wherein Q is a divalent, mononuclear or dinuclear aromatic radial which is unsubstituted or is substituted by lower alkyl groups and which can contain, as a linking member, a lower alkylene group, X is one of the groups -O-Ph-Z-Ph-O- and -OOC-(CH2)y-COO-, Ph being an optionally substituted phenylene group, Z being an alkylene group having 1-4 carbon atoms and y being a number from 2 to 12, R is a hydrogen atom or a methyl group, Y is an alkylene radical having 2-6 carbon atoms, m is an integer from 4 to 50 n is an integer from 1 to 6 and o is an integer from 4 to 20 having the properties of thermoplasts and being hardenable to give elastic products. It is suitable for use as a hardenable constituent of photopolymerizable materials.
