  • High-flow polyamides
    Patent number: 8877888
    Abstract: A polyamide modified by a multi-functional compound, and a method for producing said polyamide and compositions comprising same are described. A method for the production of a polyamide comprising linear macromolecular chains and star-shaped macromolecular chains is also described. A resulting polyamide having optimal mechanical and rheological properties in order to (i) improve mould filling speed and quality, and (ii) produce moldable compositions with high filler contents is also described.
    Type: Grant
    Filed: September 28, 2010
    Date of Patent: November 4, 2014
    Assignee: Rhodia Operations

  • HIGH-VISCOSITY POLYAMIDE
    Publication number: 20120123041
    Abstract: A polyamide, a method for manufacturing the polyamide and compositions that include the polymer are described. A high-viscosity polyamide obtained by the polymerization of diacid and diamine monomers in the presence of multifunctional and, optionally, monofunctional compounds are also described. The polyamide can be used in particular for the production of compositions intended, for example, for being molded or blown.
