Title (EN) POLYISOBUTYLENE-BASED POLYURETHANES
(FR) POLYURÉTHANES À BASE DE POLYISOBUTYLÈNE
Abstract:
(EN) An elastomeric polymer, comprising (1) a hard segment in the amount of 10% to 60% by weight of the elastomeric polymer, wherein the hard segment includes a urethane, urea or urethaneurea; and (2) a soft segment in the amount of 40% to 90% by weight of the elastomeric polymer. The soft segment comprises (a) at least 2% by weight of the soft segment of at least one polyether macrodiol, and/or at least one polycarbonate macrodiol; and (b) at least 2% by weight of the soft segment of at least one polyisobutylene macrodiol and/or diamine.
(FR) La présente invention concerne un polymère élastomère, comprenant (1) un segment dur dans une quantité allant de 10 % à 60 % en poids du polymère élastomère, le segment dur comprenant un uréthane, de l'urée ou de l'uréthane-urée; et (2) un segment souple dans une quantité allant de 40 % à 90 % en poids du polymère élastomère. Le segment souple comprend (a) au moins 2 % en poids du segment souple d'au moins un polyéther macrodiol, et/ou au moins un polycarbonate macrodiol; et (b) au moins 2 % en poids du segment souple d'au moins un polyisobutylène macrodiol et/ou diamine.
