Patent ID: 7015299

Claim:
A composition useful in preparing melt spun textile fibers comprising a polyurethane polymer consisting of the reaction product of monomers consisting of at least one diisocyanate monomer and at least two diol monomers, a first diol monomer which is a member selected from the group consisting of a polyether diol, a polyester diol, hydroxyl terminated polyether/polyester glycols and mixtures thereof; and a second diol monomer having a molecular weight of about 62 to about 118, said polyurethane having a molecular weight of about 200,000 and above, a tenacity of about 0.6 gm/denier and above, and an elongation of about 400% and above, wherein said first and second diol monomers are always reacted separately during preparation of the polyurethane polymer.
