摘要： The present invention relates to components of mobile electronic devices made of an amorphous polyamide composition characterized by excellent mechanical properties, low moisture uptake, low distortion and very good aesthetical properties. The amorphous polyamide has recurring units derived from the polycondensation of a mixture of monomers of aromatic dicarboxylic acid(s), cycloaliphatic diamine(s) with 6 to 12 carbon atoms, and a third monomer with 10 to 16 carbon atoms.

摘要： A mixture comprising at least one polymer and from 0.1 wt % to 1.5 wt %, based on the weight of the polymer, of at least one fumed silica, wherein the polymer comprises at least one semi-aromatic polyamide in an amount of more than 50 wt %, based on the weight of the polymer. The presence of the fumed silica in the semi-aromatic polyamide-based mixture allows notably for reducing the cycle time necessary for the manufacture of various shaped articles, such as mobile phone housings, by melt processing methods like injection molding.

摘要： A polymer composition having improved processing properties, in particular improved crystallization behavior, comprising a semi-aromatic polyamide and a graphene material. The graphene material may be a nano-graphene platelet. The semi-aromatic polyamide may comprise recurring units obtainable by a polycondensation reaction between at least one aromatic diamine and at least one non-aromatic diacid or derivatives thereof and/or recurring units obtainable by a polycondensation reaction between at least one aromatic diacid or derivatives thereof and at least one non-aromatic diamine. The composition may further comprise a polyamide different than the semi-aromatic polyamide. The composition may further comprise a filler.
