摘要： The present invention relates to bicomponent polymer fibers, and to processes for forming those fibers. Bicomponent polymer fibers are described, having a core comprising a core polymer and a sheath comprising a sheath polymer, wherein the sheath polymer is a polyolefm having an Mw less than about 65,000 g/mol. The core polymer has an Mw at least about 20,000 g/mol greater than the Mw of the sheath polymer. Processes for forming bicomponent fibers are also described, comprising (i) forming a molten blend of a core polymer and a sheath polymer; (ii) extruding the molten polymer blend using an extrusion die having a length to diameter ratio greater than or equal to about 10 and under shear conditions sufficient to drive the sheath polymer to the die wall; and (iii) forming meltblown fibers having a core comprising the core polymer and a sheath comprising the sheath polymer.

摘要： The present invention relates to a process for preparing a thermoplastic vulcanizate (TPV) comprising: contacting a thermoplastic polymer, a cross-linkabl elastomer, at least one curative, and at least one cure activator in a solvent to form Composition A. The solvent is then removed, and thereafter the cross-linkable elastomer is at least partially cured. The average particle size of the cross-linkable elastomer is 10 microns or less after the solvent is removed.
