摘要： A halogen-free electrically insulating film is prepared from a composition including particular amounts of a poly(arylene ether), a hydrogenated block copolymer of an alkenyl aromatic compound and a conjugated diene, and a triaryl phosphate. The electrically insulating film may be prepared by an extrusion and/or calendering method. Uses of the electrically insulating film include, for example, shielding applications in power supply housing, printed circuit board insulation, backlit aircraft in flight panels and displays, business equipment insulation, computer rack partitions, and television and monitor insulation.

摘要： A method for removing volatile components from wet, solid polymeric materials on a vacuum vented extruder is described. Polymeric materials containing substantial amounts of water, 1-20 % by weight, are rapidly converted to polymer compositions containing less than about 0.5% by weight water at high throughput rates while avoiding complications resulting from excessive steam backflow through the extruder feed throat. The method utilizes a screw design comprising only forward flighted screw elements in an initial polymer melting and kneading zone. Steam generated as the polymer is heated and sheared flows downstream to a first vacuum vent for removal. The partially devolatilized polymer melt is then subjected to additional kneading and vacuum venting. The claimed method converts wet polycarbonate powder containing residual methylene chloride to essentially dry polycarbonate powder containing less than about 1 ppm methylene chloride.
摘要翻译：描述了在真空排气的挤出机上从湿固体聚合材料中除去挥发性组分的方法。含有相当量的1-20重量％的水的聚合材料可快速转化为含有低于约0.5重量％水的聚合物组合物，同时避免由于挤出机进料喉部产生的过量蒸汽回流引起的并发症。该方法采用在初始聚合物熔融和捏合区域中仅包括前向螺旋元件的螺杆设计。当聚合物被加热和剪切时产生的蒸汽流向下游到第一真空排气口以除去。然后将部分脱挥发分的聚合物熔体进行额外的捏合和真空排气。要求保护的方法将含有残余二氯甲烷的湿聚碳酸酯粉末转化为含有少于约1ppm二氯甲烷的基本上干燥的聚碳酸酯粉末。
