Abstract:
1. A hydrophilic or hydrophobic polyurethane having at least one olefinically unsaturated group selected from the group consisting of pendant olefinically unsaturated groups, terminal olefinically unsaturated groups, and mixtures thereof, wherein the pendant olefinically unsaturated groups are selected from the group consisting of pendant olefinically unsaturated groups which are attached to a cycloaliphatic group which represents a link in the polymer main chain end pendant olefinically unsaturated groups which are present as a double bond in a cycloolefinic group which constitutes a link in the polymer main chain, and the terminal olefinically unsaturated groups are selected from the group consisting of terminal olefinically unsaturated groups which are attached to a cycloaliphatic group which forms an endgroup of the polymer main chain and terminal olefinically unsaturated groups which are present as a double bond in a cycloolefinic structure which forms an endgroup of the polymer main chain.
