| titleOfInvention | High strength polyisobutylene polyurethanes |
| abstract | 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, wherein the soft segment includes a polyisobutylene macrodiol and/or diamine. Additionally disclosed is a method of forming a polyisobutylene-based thermoplastic urethane, comprising the steps of (a) reacting a polyisobutylene macrodiol and/or diamine with a diisocyanate to form a first reaction mixture; (b) combining a metal catalyst and a chain extender with the first reaction mixture to create a second reaction mixture, a molar ratio of the metal catalyst to the diisocyanate being greater than 0.0:1 and less than or equal to 0.4:1; and (c) reacting the second reaction mixture for a period of time sufficient to form the polyisobutylene-based thermoplastic urethane. |
