CA 2745897
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.
L'invention concerne un nouveau macromère ou un mélange de macromères comprenant des fractions terminales éther d'isocyanatophényle et au moins deux résidus d'un polymère hydrosoluble présentant un poids moléculaire variant de 80 à 10 000 à proximité du groupe éther des fractions isocyanate terminales éther d'isocyanatophényle, ce qui forme au moins deux liaisons éther dans le macromère ou le mélange de macromères. L'invention concerne également un procédé de préparation d'un macromère polyisocyanate.
