Patent ID: 7202322

Claim:
A breathable article comprising: (a) at least one layer of fabric and (b) at least one layer of thermoplastic polyurethane polymer, wherein said polyurethane polymer is a polyether polyurethane derived from at least one diisocyanate reacted in a one-shot process with at least one hydroxyl terminated aromatic glycol chain extender selected from the group consisting of 1,4-di(hydroxymethyl) benzene, 1,2-di(hydroxymethyl) benzene, 1,4-di(2-hydroxyethoxy) benzene, 1,3-di(2-hydroxyethyl) benzene, 1,2-di(2-hydroxyethoxy) benzene, and combinations thereof, and at least one hydroxyl terminated polyether polyethylene glycol intermediate containing an alkylene oxide having the formula (CH 2 ) x —O y wherein x is 2 and y is an integer from 11 to 115 wherein the amount of aromatic glycol chain extender used is from about 1.2 to about 1.8 moles per mole of hydroxyl terminated polyether intermediate and the mole ratio of the at least one diisocyanate used is from about 0.95 to about 1.05 moles of diisocyanate per mole of the total moles of the one or more hydroxyl terminated polyether intermediate and the one or more hydroxyl terminated aromatic glycol chain extender.
