This invention relates to mixtures of polyarylene sulphides, nitroarylmethylidene ketones, glass fibers and optionally other fillers. The mixtures are distinguished by good mechanical properties.
摘要:
The invention releates to oligo- and polyarylene sulfides, preferably polyphenylene sulfides, terminated by sulfonic acid and/or sulfonic acid derivative groups, to their production and to their use for the production of new polymers and new polymer mixtures.
摘要:
The invention relates to a process for the production of linear, unbranched polyarylene sulfides from aromatic dichlorine compounds and alkali sulfides in tetra-alkylated, cyclic ureas as the reaction medium.
摘要:
The invention relates to low-viscosity polyarylene sulfides (PAS), preferably polyphenylene sulfides (PPS), which are produced with cycloaliphatic, unsaturated acids as molecular weight regulators.
摘要:
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.
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:
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:
The invention relates to linear and branched poly-p-arylene sulfides (PAS), preferably poly-p-phenylene sulfides (PPS), which have an extremely low proportion of defect or foreign structures, to a process for their production and to their use for the production of molded articles.
摘要:
The invention concerns a process for the manufcture of polyarylene sulphides from alkali sulphide and aromatic dihalogen compounds, whereby the alkali sulphide is produced in situ.
