  • 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.

  • Patent number: 5824254
    Abstract: Process for moulding a thermoplastic material by injection onto a rotating core, in which the relative rotation of the various parts of the mould takes place during at least a part of the dwell stage and ends before the end of this stage. This process, which yields good results with polyolefins, makes it possible to manufacture articles such as receptacles and cylinders, exhibiting good mechanical properties.
