摘要： A process for preparing modified polymer by withdrawing a slip stream of polymer melt from the discharge line of a continuous polymerization reactor, admixing in a highly modified polymeric additive into the polymer melt within the slip stream, then introducing the modifier containing slip stream late in the manufacturing process prior to the slip stream withdrawal point. The improved processes of the invention have particular utility for large-scale, continuous reactor where transitions and short production runs are economically prohibitive thereby limiting the product breath. The process is particularly suited for producing a family of copolyesters using a continuous melt phase production process.

摘要： An apparatus for distributing a second material into a flow stream of a first material includes a distributor plate assembly coupled to an additive enriched stream. The distributor plate assembly is mounted within a vessel for a flow stream and distributes the additive enriched stream at various locations within the flow stream of the first material.

摘要： A polyester polymer composition containing polyester polymers such as polymers having repeating ethylene terephthalate units, aluminum atoms in an amount of at least 3 ppm based on the weight of the polymer, the polyester polymers having an It.V. of at least 0.72 dL/g obtained through a melt phase polymerization and a residual acetaldehyde level of 10 ppm or less. Also provided are polyester polymer compositions containing polyester polymers and: (i) aluminum atoms (ii) alkaline earth metal atoms or alkali metal atoms or alkali compound residues, and (iii) a catalyst deactivator such as a phosphorus compound. The phosphorus compound is added to the polyester melt either late in the polycondensation or upon remelting a solid polyester polymer. The polyester polymer exhibits good L* brightness, clarity, and low levels of acetaldehyde generated upon melting.

摘要： A material-processing system includes a material processor configured to discharge a first material. Additionally, the material-processing system may include a passage, and the material-processing system may be configured to direct at least a portion of the first material discharged from the material processor through the passage. The material-processing system may also include a nozzle having an outlet in fluid communication with the passage. The material-processing system may also include a fluid-supply system configured to direct a fluid additive through the nozzle into the passage. Additionally, the nozzle may be insulated in a manner that slows heat transfer to the nozzle from the first material or the fluid additive.
