Abstract:
1. A polymer melt composition suitable for spinning fibers and being free of thermoplastic, water-insoluble polymers, the composition comprising: a. an uncrosslinked melt processed hydroxyl polymer in a flowable state selected from the group consisting of: starch, starch derivatives and mixtures thereof; b. an external plasticizer comprising water; and c. a crosslinking system comprising an unactivated crosslinking agent comprising an imidazolidinone for crosslinking the uncrosslinked melt processed hydroxyl polymer, wherein the polymer melt composition exhibits a pH of about 5 or less and a normalized shear viscosity change of less than 1.3 times the polymer melt composition's initial shear viscosity after 70 minutes according to the Shear Viscosity Change Test Method.
