ABSTRACT:
Polymer blends obtainable by thermal treatment, at not less than 150.degree. C., of a mixture containing at least one high-performance polymer and from 15 to 99 parts by weight or preferably from 40 to 90 parts by weight and particularly preferably from 55 to 75 parts by weight, of a polymer containing sulfoxide groups, and crosslinked or partly crosslinked polymer blend obtainable by thermal treatment, at not less than 150.degree. C., of a mixture containing at least one of the high-performance polymers polyesters, partly fluorinated polymers, polyethersulfones, polysulfones, polyetherimides, polyamidoimides or polyacetals and at least one polymer containing sulfoxide groups, are distinguished by high thermal and chemical stability. Polymers containing sulfoxide groups are polyarylene sulfoxides, in particular polyphenylene sulfoxide. The polymer blends are used for the production of fibers, films or shaped articles.
