  • Poly(arylene ether) articles and compositions
    Patent number: 8110632
    Abstract: A profile extruded article includes a composition that is formed by melt-kneading particular amounts of a poly(arylene ether), a polystyrene-poly(ethylene-butylene)-polystyrene triblock copolymer, a homopolystyrene, and a polysalicylate. The article is particularly useful in the fabrication of solar collectors for low cost solar energy systems.
    Type: Grant
    Filed: January 15, 2009
    Date of Patent: February 7, 2012
    Assignee: Sabic Innovative Plastics IP B.V.
    Inventors: Christian Lietzau, Vijay R. Mhetar, Abhijit Namjoshi, Geuch Zijlma
  • Poly(arylene ether) composition and article
    Patent number: 7902296
    Abstract: A composition includes specific amounts of a high molecular weight poly(arylene ether), a rubber-modified polystyrene, and a hydrogenated block copolymer. The use of the high molecular weight poly(arylene ether) unexpectedly provides substantially improved durability to articles molded from the composition. The composition is particularly useful for molding hot water pipes and fittings.
