A breathable article comprising: (a) at least one layer of tissue and (b) at least one layer of a thermoplastic polymer that has no holes or pores comprising: a polyurethane polyether derived from - at least one aromatic diisocyanate that has reacted with at least one hydroxyl-terminated aromatic glycol chain extender selected from the group consisting of 1,4-di (2-hydroxyethoxy) benzene, 1,3-di (2-hydroxyethoxy) benzene, 1,2-di (2- hydroxyethoxy) benzene, and combinations thereof, and - at least one hydroxyl terminated polyether intermediate containing an alkylene oxide with the formula in which x is 2 and y is an integer from 11 to 115, in which The amount of aromatic glycol chain extender used is 1.2 to 1.8 moles per mole of hydroxyl terminated polyether intermediate, and the mole ratio of said diisocyanate is 0.98 to 1.03 moles per mole of the total moles of said polyether intermediate and di cho aromatic chain extender. |
