摘要： A method for separating polymers from a physically commingled solid mixture containing a plurality of polymers comprises dissolving a first one of the polymers in a solvent at a first lower temperature to form a first preferably single phase solution and a remaining solid component. The solid component contains additional polymers which are not soluble to the solvent at the first temperature but which may be soluble at higher temperatures. The method includes subsequently heating the solvent to dissolve additional polymer from the solid component to form subsequent solutions. The polymers are then separated from their respective solution either using flash evaporation techniques when more than one polymer has been dissolved at a single temperature, or conventional techniques for extracting a polymer from a solvent in a solution.

摘要： A method of producing an impact modified polymer comprises dissolving a high-temperature polyetherimide and a high-temperature fluorelastomer in a common solvent to form a single phase solution which is heated to a temperature that would normally vaporize the solvent. The solution is maintained at an elevated pressure to avoid vaporization of the solvent. After being heated at the elevated temperature, the solution is subjected to flash evaporation by introducing the solution into a zone of reduced pressure. This forms a blend of the polyetherimide into which the fluorelastomer is micro-dispersed. A composition of matter formed by the method advantageously includes a solid component having 90% by weight ULTEM 1000 polyetherimide and 10% by weight VITON A fluorelastomer. Dimethyl formamide is advantageously used as the common solvent.
摘要翻译：制备抗冲改性聚合物的方法包括将高温聚醚酰亚胺和高温热稳定剂溶解在常用溶剂中以形成单相溶液，该单相溶液被加热到通常使溶剂蒸发的温度。将溶液保持在升高的压力下以避免溶剂蒸发。在升高的温度下加热后，通过将溶液引入减压区中使溶液进行闪蒸。这形成了其中微分散的荧光体的聚醚酰亚胺的共混物。通过该方法形成的物质组合物有利地包括具有90重量％ULTEM 1000聚醚酰亚胺和10重量％VITON A荧光体的固体组分。二甲基甲酰胺有利地用作常用溶剂。
