Abstract
A composition based on aliphatic polycarbonates containing urethan groups and acrylic or metacrylic end groups, to be cross-linked in the presence of radicalic initiators for their functionalization with acrylic or metacrylic groups of a mixture composed of diols, polyols and their oligomeric derivatives terminated by OH groups and containing in their molecule carbonate groups and urethan groups.
