    摘要: An apparatus is described having an extrusion means for extruding a molten polymer strand; a pelletizer; and a trough disposed to convey a polymer strand from the extrusion means to the pelletizer; the trough has an interior bottom surface; a water dispensing means disposed to provide a layer of water on a first portion of the interior bottom surface that is proximate to the extrusion means; a mesh or perforated surface disposed in the trough downstream from the water dispensing means, disposed to permit the separation of water from a water-immersed strand incident upon it; and a second portion of the interior bottom surface downstream from that mesh or perforated surface, disposed to contain a layer of water.

    摘要: The process creates a radial temperature gradient in an extruded strand in a direction normal to the direction of motion thereof (that is, normal to the longitudinal direction thereof) so that upon exiting the first quench region the surface of the strand has solidified while at least the preponderant portion of the interior of the strand remains above the cold crystallization temperature, Tcc Then, in the annealing region, heat from the warmer interior will be transferred to the cooler surface, causing the surface to heat up into the range of Tcc, thereby inducing the surface to undergo crystallization. Once the surface has undergone crystallization, the strand is thoroughly quenched in a second quench region so that the strand will be ready for pelletization, accumulation or other handling steps.

    摘要: Provided are polyester compositions comprising poly(trimethylene terephthalate) and flame retardant additives that are phosphonic acid esters. The compositions can be used to make articles having reduced flammability and reduced yellowness as compared to conventional poly(trimethylene terephthalate) compositions.
