A foamed polyarylene sulfide according to the invention has a density which is reduced by at least 50% compared with the theoretical density of nonfoamed material, and is expediently produced by subjecting a polyarylene sulfoxide as such or a mixture of one or more polyarylene sulfides with a polyarylene sulfoxide to heat treatment. The temperature of the heat treatment is in the range from 250.degree. to 400.degree. C.

Polyarylene sulfide foams and a process for their production

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.

New complexes of the elements of Groups VIIA, VIIIA, and IB of the Periodic Table* with the trisodium salt of tris(m-sulfophenyl)phosphane as a complex ligand. The complexes are used as catalysts for hydrogenations for the water gas reactions, hydrocarbonyls, hydroformylations, oxidations, carbon-carbon cross-linking reactions (e.g. allene/alkine coupling), and additions of secondary amines to carbon-carbon double bonds.
