    Patent number: 10513576
    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. 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.
