    摘要: The present invention provides a high strength autogenously bonded nonwoven fabric containing single polymer conjugate fibers which have at least two substantially the same component compositions, wherein the component compositions of the fibers contain one thermoplastic polymer selected from the group consisting of semicrystalline thermoplastic polymers, crystalline thermoplastic polymers and blends thereof. The component compositions are processed with substantially identical processing conditions to form the fibers and have substantially the same melt flow rate as measured in accordance with the ASTM 1238-65T testing procedure.

    摘要: A stabilizer formulation particularly well suited for improving the properties of thermoplastic polymers is disclosed. The stabilizer formulation contains a combination of stabilizers that improves the process stability of a polymer, prevents the polymer from yellowing, increases the thermal aging stability of the polymer and inhibits the polymer from generating smoke during melt processing. Of particular advantage, the stabilizer formulation improves the stability of a polymer without significantly adversely affecting any other properties of the polymer. In one embodiment, the stabilizer formulation includes a hindered amine, a hydroxyl amine, and one or more hydrolytically resistant phosphites. In one embodiment, the formulation can further contain an acid scavenger for preventing an acid contained within the polymer or produced during processing from harming the polymer.
