Publication number: 20120115968Abstract: A seed beads dispersing disperse system is obtained by dispersing olefin resin seed beads 1 with a specific tubular shape in an aqueous medium. Then, the olefin resin seed beads 1 are impregnated with styrene monomers and the styrene monomers are polymerized in the presence of a polymerization initiator by heating at a temperature in a specified range, to thereby obtain tubular thermoplastic resin composite beads. Expandable thermoplastic resin composite beads obtained by impregnating the thermoplastic resin composite beads with a blowing agent, expanded thermoplastic resin composite beads obtained by foaming and expanding the expandable thermoplastic resin composite beads, and a foamed molded article formed from the expanded thermoplastic resin composite beads by molding are also obtained.Type: ApplicationFiled: November 7, 2011Publication date: May 10, 2012Applicant: JSP CORPORATIONInventors: Masaomi SHIMA, Mitsuru Shinohara

Publication number: 20120071592Abstract: The invention is a composition that can prevent formation in, or scavenge undesirable organic materials from, a polymer matrix. The composition contains cyclodextrin and particles of activated carbon. The composition can scavenge thermal decomposition products that can be produced during melt processing of a polymer, contaminants inherent in a polymer, or other types of impurities from a polymer matrix that otherwise may elute into the air, a water supply, or an ingestible material such as a food, a drug, or a beverage. Other aspects of the invention are blends of the composition with polymeric materials, methods of making blends, articles containing the composition, and methods of making articles containing the composition.Type: ApplicationFiled: November 23, 2011Publication date: March 22, 2012Applicant: CELLRESIN TECHNOLOLGIES, L.L.C.Inventor: Willard E.
