Abstract
An article is prepared by injection molding, wherein the article is formed from a hydrophilic thermoplastic polyurethane composition, wherein the thermoplastic polyurethane composition comprises the reaction product of a hydroxyl terminated polyol intermediate component, an aliphatic isocyanate component, and, optionally, a chain extender component. For injection molding, the hydrophilic thermoplastic polyurethane has a crystallization temperature measured by dynamic scanning calorimetry of at least 75° C.
