the present invention discloses a thermoplastic polyurethane which is comprised of the reaction product of a hydroxyl terminated polyester intermediate , a polyisocyanate , and a glycol chain extender ; wherein the hydroxyl terminated polyester intermediate is comprised of repeat units that are derived from 1 , 3 - propylene glycol and a dicarboxylic acid ; wherein the hydroxyl terminated polyester intermediate has a number average molecular weight from 500 to 10 , 000 ; and wherein the thermoplastic polyurethane includes hard segments that are the reaction product of the polyisocyanate and the glycol chain extender . this thermoplastic polyurethane is unique in that it has a greatly reduced tendency to bloom . this is highly desirable in applications where high clarity is desired because blooming causes articles containing the thermoplastic polyurethane to be hazy or foggy in appearance . blooming can also reduce the ability of an article made with the thermoplastic polyurethane to be securely bound to another article with an adhesive .
