摘要:
Organic polymers, for example thermoplastics, thermosetting resins, elastomers or lacquers with increased electrical conductivity, characterized by a content of sulphur-containing pyropolymers which have been obtained by pyrolysis of sulphur-containing condensation products of aromatic compounds, which optionally contain hereto-cyclic rings with O, S or N as hetero-atoms and, sulphur or sulphur releasing compounds.
摘要:
The invention relates to highly crystalline, rapid-crystallizing, thermoplastic compositions of polyphenylene sulphides and aromatic phosphoric acid esters.
摘要:
Small quantities of hydrogenated polybenzyls act as a perfect mould release agent for aromatic polyesters based on diphenols and iso- and/or terephthalic acids and do not appreciably impair the elastic strength characteristics, the dimensional stability under heat and the transparency.
摘要:
High-molecular polyesters which are distinguished by good processability, a high glass transition temperature, mechanical strength and clear transparency are reproducibly obtained by transesterifying and polycondensing bisphenols with diaryl terephthalates and/or diaryl isophthalates in the presence of an aromatic polycarbonate having a molecular weight of 600 to 15,000.
摘要:
Thermoplastic polyalkyleneterephthalate moulding compounds prepared by blendingA) 99.9 to 80.0% by weight of one or more thermoplastic polyalkyleneterephthalates andB) 0.1 to 20.0% by weight of an epoxy/isocyanurate resin in the melt.
摘要:
The invention relates to highly crystalline, rapid-crystallizing, thermoplastic compositions of polyphenylene sulphides and carboxylic acid esters or carbonic acid esters.
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.
