  • Patent number: 6706790
    Abstract: The present invention relates to a polyamide-based composition used for the manufacture of moulded components exhibiting high resistance to attack by light and/or weathering. The invention more particularly relates to compositions comprising a thermoplastic matrix based on semi-crystalline polyamide, a black pigment and optionally reinforcing fillers. This composition is characterized by the presence of thermally stabilizing additives, in combination with a black pigment comprising at least one black pigment of inorganic origin and with at least additives which decrease the effect of radiation on the degradation of the polymeric matrix. The compositions of the invention exhibit improved stability in their properties under the effect of light and/or weathering, for example similar to that of polyester.

  • Publication number: 20030050433
    Abstract: Polyisobutylene (PIB) functionalized with terminal reactive unsaturation is disclosed. Carbocationically polymerized monohalogen-terminated PIB is dehydrohalogenated in a hydrocarbon solvent using an alkoxide of the formula RO-M wherein R is alkyl of at least 5 carbon atoms and M is alkali metal. The PIB obtained has terminal unsaturation which is 100% in the reactive ‘exo’ form which can be converted to succinic anhydride groups (PIB-SA) by the ene reaction with maleic anhydride. The PIB-SA is reactive with amine functional dendrimers to obtain a star-branched polymer having a dendrimer core and PIB branches joined by succinimide linkages. Blends of the star-branched polymer with polypropylene have improved energy absorption properties and controllable moisture/oxygen permeabilities useful in films.
