Method of making powder compositions of aromatic polyethersulphone and filler, compositions made by the method, and articles made from the compositions.

摘要

Production of a compression or sinter-mouldable powder composition of polyethersulphone homopolymer having repeat unit -Ph-O-Ph-SO2- (-Ph- is p-phenylene) and a powder filler by (a) preparing a viscous but stirrable dispersion of the filler in dichloromethane which dispersion contains said polyethersulphone, (b) stirring the dispersion to produce a soft solid which breaks down into a powder, and (c) removing residual dichloromethane.
