ABSTRACT:
The invention relates, by way of new products, to poly-(carbonate-urethanes) with acrylic or methacrylic acid terminal groups, of the formula ##STR1## in which X represents either hydrogen or the methyl group, R represents a substituted or unsubstituted alkylene, cycloalkylene or arylene radical, R' represents a lower alkylene radical, Z represents a polycarbonate chain and C, H, N and O respectively represent carbon, hydrogen, nitrogen and oxygen.
The unsaturated poly-(carbonate-urethanes) according to the invention are obtained by condensing a diisocyanate with a polycarbonate-diol and a lower hydroxyalkyl acrylate or methacrylate.
They constitute a base for photocrosslinkable compositions which resist hydrolysis and possess a good adhesion.
