ABSTRACT:
Blooming in certain thermoplastic polyurethane products is substantially or completely eliminated by including a chain terminator. More specifically, at least one hydroxy functional polyester polyol having a molecular weight of at least 500 and a hydroxyl functionality of at least 2, a chain extender and an organic diisocyanate are combined with a chain terminator. The chain terminator which is preferably a monofunctional compound that is reactive with an isocyanate. These reactants are used in amounts such that the of NCO/H index of the formulation is at or near 100.
