摘要 |
A concentrate of poly(trimethylene arylate), particularly poly(trimethylene terephthalate) and polystyrene containing 15 to 40 wt % polystyrene is employed in the production of shaped articles such as films, pellets, and fibers. In one embodiment the concentrate is melt mixed with a polymeric diluent comprising a poly(trimethylene arylate) to form a spin blend comprising 0.5 to 1.5 wt % polystyrene, and the spin blend is extruded through a spinneret comprising a plurality of identical orficies, producing a plurality of filaments. |
