    摘要： A fiber comprises a composition including a poly(phenylene ether) having less than or equal to 240 parts per million by weight of hydroxyl groups associated with ethylene bridge groups and less than or equal to 800 parts per million by weight of hydroxyl groups associated with rearranged backbone groups, both amounts based on the weight of the poly(phenylene ether). Fiber of low denier can be formed from this composition. The fiber can be formed by melt spinning.

    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.
