    摘要: This invention relates to new high molecular weight, optionally branched co-polyarylene sulphides prepared by the reaction of halogenated aromatic compounds and dihalogenated phenyl-pyrazole-3-ones in a polar solvent with the addition of 0.2 to 100 mol %, based on the dihalogenated aromatic compound, of an amino acid to the reaction mixture, and to the use of these copolyarylene sulphides as embedding compounds for electronic parts.
