A thermoplastic polyurethane composition having a high crystalline content which
advantageously can be processed in an extruder. The composition includes a crystallization
retarding component of a short chain or monomeric diol which is branched, substituted
or contains heteroatoms, or a combination thereof. The crystallization retarding
component delays the onset of crystallization during extrusion processing until
the composition has exited the extruder.
