This invention relates to crystalline, thermoplastic moulding compounds of polyphenylene sulphide (PPS) and aliphatically saturated carboxylic acid esters. The moulding compounds have increased tracking resistance.

Polyphenylene sulphide moulding compounds with improved electrical

The invention relates to mixtures of polyarylene sulphides, maleimides, glass fibres and if appropriate other additives. The mixtures are distinguished by good mechanical properties.

Mixture of polyarylene sulphides, glass fibres and maleimides

The invention relates to blends of polyarylene sulfides, epoxides, anhydrides, glass fibers and optionally other fillers. The blends are distinguished by good mechanical properties.

Blends of polyarylene sulfides, epoxides, anhydrides, glass fibers and

Circuit boards having excellent electrical and mechanical properties are obtained when special mixtures of polyarylene sulfides and polycarbonates, polyaryl ethers, polyamides, polyesters or rubber elastomers are used as base plates for the wet-chemical deposition of the circuits and the boards are treated with an oxidizing agent before activation.

Process for the metallization of moldings of polyarylene sulfides

The invention relates to mixtures of polyarylene sulphides, heterocyclic nitryoaryloxy compounds and optionally other additives. The mixtures are distinguished by good mechanical properties.

Mixtures of polyarylene sulphides, glass fibres and heterocyclic

The invention relates to conductive blends made from polyarylenesulphides, preferably polyphenylenesulphides (PPS) with graphite and conductive carbon black.

Conductive polyarylenesulphide mixtures containing carbon

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.

Filled thermoplasts with low shrinkage anisotropy

The invention relates to blends of polyarylene sulfides, epoxides, glass fibers, optionally anhydride-containing polymers and optionally other additives. They are distinguished by good mechanical properties.

Blends of polyarylene sulfides, epoxides, glass fibers, optionally

By treating aromatic polycarbonates, aromatic polyester carbonates and aromatic and/or araliphatic polyesters in the molten state with super-critical gases or gas mixtures under pressure, the melt viscosity of these polymers is considerably lowered so that basic chemical operations which proceed only incompletely under the usual conditions can be carried out on these thermoplasts.

Process for lowering the melt viscosity of aromatic polycarbonates,

The invention relates to conductive blends of polyarylene sulfides (PAS), preferably polyphenylene sulfide (PPS), with graft polymers, conductive carbon black and graphite.

Elastomer-modified carbon-containing polyarylene sulfide blends

The invention relates to a process for the production of vinyl copolymers with grafted-on polycarbonate chains, to the grafted vinyl copolymers obtainable by the process according to the invention, to their use as modifiers for mixtures of thermoplastic polycarbonates and thermoplastic polystyrenes, to such mixtures themselves and to the use of such mixtures as substrates for optical discs.

Vinyl copolymers with grafted-on polycarbonate chains, their production

The present invention relates to thermoplastic mixtures of 90 to 20% by weight of an aromatic polycarbonate with an Mw of 15,000 to 25,000 and p-(iso-C.sub.8 -C.sub.9 -alkyl)-phenyl end groups and 10 to 80% by weight of a polystyrene with an Mw of 80,000 to 400,000, and to their use as substrates for optical data memories.
