The invention relates to polyarylene sulfides (PAS), preferably polyphenylene sulfide (PPS), reduced in viscosity by aftertreatment of the PAS formed in the production process with disulfides in the melt.

Polyarylene sulfides reduced in viscosity by aftertreatment with

Thermoplastic polyalkyleneterephthalate moulding compounds prepared by blending

Thermoplastic polyalkyleneterephthalate moulding compounds

The invention relates to a mixture of PPS and colophony which shows improved color stability during processing at high temperatures.

Color-stabilizing polyarylene sulfide mixture

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 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.

Coatings based on polyarylene sulfides

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.

Two-component injection molding with 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 molding compounds of polyarylene sulfides (PAS), preferably polyphenylene sulfides (PPS), which have a low ion content and delayed crystallization and to their use as an encapsulating compound for active and passive electronic components.

Polyarylene sulfide molding compounds and their use as an encapsulating

1,4-Dihydroxynaphthalene, iron compounds and optionally tertiary arylamines prove to be a highly active accelerator/stabilizer system for peroxide-catalyzed ethylenically unsaturated hardenable compounds.

Use of 1,4-dihydroxynaphthalene in the hardening of ethylenically

Anilines substituted in the m- and p-position by an alkyl radical and a halogen atom are eminently suitable for use as accelerators for cold-hardening unsaturated polyester resins.

Use of 3,4-disubstituted anilines as accelerators for unsaturated

Highly reactive unsaturated polyesters for air-drying polyester resins can be obtained by reacting .beta.,.gamma.-ethylenically unsaturated ether alcohols with a polyester precondensate.

Process for the production of polyesters for air-drying unsaturated

Mixture of I. nucleus-unsubstituted or m-substituted N.N-dialkanol arylamides and II. p-substituted arylamines obtained by reaction of I. with diisocyanates and/or dicarboxylic acids work as excellent accelerators in unsaturated polyester resin compositions which then show a favorable pot-life, high stability in storage and rapidly obtainable sandability.
