    • Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, a polystyrene/polyethylene oxide copolymer, and optionally, an infrared attenuating agent, are provided. In exemplary embodiments, the blowing agent includes at least one hydrofluorocarbon blowing agent. The maleic anhydride-styrene copolymer grafted with polyethylene oxide provides a water vapor permeability of 1.1 perm inch or greater in the extruded foam product without detrimentally affecting physical or thermal properties of the product. Additionally, the copolymer of maleic anhydride-styrene grafted with polyethylene oxide has a positive affect on the processability of the blowing agent(s) in the composition by both widening the process window and enhancing the solubility of the blowing agent in the polymer melt. Thus, the polystyrene/polyethylene oxide copolymer present in the inventive composition acts as a cell enlarger, a plasticizer, and a processing aid. A method of forming an extruded foam product is also provided.
    • 提供含有可发泡聚合物材料,至少一种发泡剂,聚苯乙烯/聚环氧乙烷共聚物和任选的红外衰减剂的聚合物泡沫和聚合泡沫产品。 在示例性实施方案中,发泡剂包括至少一种氢氟烃发泡剂。 用聚环氧乙烷接枝的马来酸酐 - 苯乙烯共聚物在挤出的泡沫产品中提供1.1 perm英寸或更大的水蒸汽透过率,而不会有害地影响产品的物理或热性能。 此外,接枝聚环氧乙烷的马来酸酐 - 苯乙烯的共聚物通过加工工艺窗口和提高发泡剂在聚合物熔体中的溶解度而对组合物中的发泡剂的加工性具有积极的影响。 因此,存在于本发明组合物中的聚苯乙烯/聚环氧乙烷共聚物用作电池放大器,增塑剂和加工助剂。 还提供了一种形成挤出泡沫产品的方法。

    • Resin beads having an average particle size of from 0.001 mm to 10 mm and containing a continuous phase and a particulate dispersed phase are described. The continuous phase includes elastomeric polymers; the dispersed phase includes homopolymers and/or copolymers containing repeat units resulting from the polymerization of one or more aryl polymerizable monomers. The unexpanded polymer resin beads can be prepared by dispersing an organic phase containing elastomeric polymers and one or more monomers, into droplets and polymerizing the monomers in the organic droplets in a low shear flow pattern. The beads can be impregnated with blowing agents, expanded and can be used to make molded articles. Resin beads having a continuous phase comprising a nitrile rubber, and a dispersed phase comprising one or more homopolymers and/or copolymers containing repeat units resulting form the polymerization of one or more aryl polymerizable show prolonged retention of blowing agents in unexpanded form.
    • 描述平均粒度为0.001mm至10mm并且包含连续相和颗粒分散相的树脂珠。 连续相包括弹性聚合物; 分散相包括由一种或多种芳基可聚合单体聚合得到的含有重复单元的均聚物和/或共聚物。 未膨胀的聚合物树脂珠可以通过将含有弹性体聚合物和一种或多种单体的有机相分散在液滴中并以低剪切流动模式将有机相聚合在有机液滴中来制备。 珠可以用发泡剂浸渍,膨胀并可用于制造模制品。 具有包含丁腈橡胶的连续相的树脂珠粒和包含一种或多种含有形成聚合一个或多个芳基可聚合的重复单元的均聚物和/或共聚物的分散相显示出未发泡形式的发泡剂的延长保留。
