摘要:
The invention relates to new sulphur-containing copolymers, a process for their preparation from a sulphur source and a mixture of dihalogenoaromatics and dihalogenoaliphatics and their use for the production of shaped articles.
摘要:
The invention relates to a process for the production of high molecular weight, optionally branched polyarylene sulfides having a low content of organically bound halogen. They are prepared by reaction of alkali sulfides and/or alkali hydrogen sulfides with aromatic dihalogen compounds in a polar organic solvent.
摘要:
This invention relates to a process for the production of high molecular weight, optionally branched polyarylene sulfides having a reduced content of extractable oligomeric constituents. They are prepared by reaction of alkali sulfides and/or alkali hydrogen sulfides with aromatic dihalogen compounds in a polar organic solvent.
摘要:
A composition useful in producing molded articles, fibers and sheet products is a mixture of from 20 to 80% by weight of polyarylene sulphides, from 10 to 60% by weight of glass fibers and from 60 to 10% by weight of mica.
摘要:
The invention relates to two-component injection-molded articles in which polyarylene sulfides (PAS), preferably polyphenylene sulfide (PPS), are present as at least one component and to a process for their production.
摘要:
The invention relates to coatings based on linear, high molecular weight polyarylene sulfides, preferably PPS, by extrusion coating of, for example, elongate stock in the form of, for example, wires, strands, optical fibers, etc.
摘要:
The invention relates to highly crystalline, rapid-crystallizing, thermoplastic compositions of polyphenylene sulphides and aromatic phosphoric acid esters.
