  • Polymer compositions comprising semi-aromatic polyamides and graphene materials
    Patent number: 9139732
    Abstract: 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.

  • POLYMER MIXTURE
    Publication number: 20130310511
    Abstract: 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.
