Abstract
A novel macromer or mixture thereof is described herein, comprising isocyanatophenyl ether terminal moieties and at least two residues of a water-soluble polymer having a molecular weight ranging from 80 to 10,000 adjacent to the ether group of the isocyanatophenyl ether terminal isocyanate moieties, thereby forming at least two ether linkages in the macromer or mixture thereof. A method for making a polyisocyanate macromer is also described herein.
