Title (EN) POLYURETHANE POLYMERS COMPRISING POLYSACCHARIDES
(FR) POLYMÈRES DE POLYURÉTHANE COMPRENANT DES POLYSACCHARIDES
Abstract:
(EN) Disclosed herein are polyurethane polymers comprising at least one polyisocyanate, a polysaccharide comprising: poly alpha-1,3-glucan; a poly alpha-1,3-glucan ester compound as disclosed herein; poly alpha-1,3-1,6-glucan; water-insoluble alpha-(1,3-glucan) polymer having 90% or greater alpha-1,3-glycosidic linkages, less than 1% by weight of alpha-1,3,6-glycosidic branch points, and a number average degree of polymerization in the range of from 55 to 10,000; dextran; or a poly alpha-1,3-glucan ether compound as disclosed herein; and optionally, at least one polyol. Also disclosed are polyurethane compositions comprising the polyurethane polymer and a solvent, as well as polyurethane foams, adhesives, coatings, films, and coated fibrous substrates comprising the polyurethane polymer.
(FR) L'invention concerne des polymères de polyuréthane comprenant au moins un polyisocyanate, un polysaccharide comprenant : du poly-alpha-1,3-glucane ; un composé ester de poly-alpha-1,3-glucane tel que décrit dans la description ; du poly-alpha-1,3-1,6-glucane ; un polymère d'alpha-(1,3-glucane) insoluble dans l'eau présentant 90 %, ou plus, de liaisons alpha-1,3-glucosidiques, moins de 1 % en poids de points de ramification alpha-1,3,6-glycosidiques et un degré numérique moyen de polymérisation dans la plage de 55 à 10.000 ; du dextrane ; ou un composé poly-alpha-1,3-glucane-éther tel que décrit dans la description ; et, éventuellement, au moins un polyol. L'invention concerne également des compositions de polyuréthane comprenant le polymère de polyuréthane et un solvant, ainsi que des mousses de polyuréthane, des adhésifs, des revêtements, des films et des substrats fibreux revêtus comprenant le polymère de polyuréthane.
