Abstract
Abstract Binary and tertiary mixtures comprise (A) from 33 to 99% by weight of at least one polyarylene sulfone, (B) from 1 to 67% by weight of at least one polyarylene sulfoxide and/or (C) from 1 to 67% by weight of a polyarylene sulfide, where the sum of the components (A), (B) and (C) is always 100%. These mixtures can be processed to give homogeneous shaped parts, which are converted by the processing procedure into homogeneous polymer masses and only have the glass transition temperature of the polyarylene sulfone.
