    Abstract: Intercalated layered materials prepared by reacting the layered material with a coupling agent and co-intercalating an onium ion and an oligomer or polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 Å, preferably at least about 5 Å, usually preferably to a d-spacing of about 15-20 Å, e.g., 18 Å with the onium ion spacing/compatibilizing agent. The intercalation of the oligomer or polymer then increases the spacing of adjacent layers an additional at least 3 Å, e.g., to at least about 20 Å, preferably about 25 Å to about 30 Å, generally about 28 Å, and provides a nanocomposite having increased tensile strength, flexibility, and ductility (less brittle).

  • Patent number: 6228911
    Abstract: The invention relates to a composition comprising a) a styrene, &agr;-methylstyrene or p-methylstyrene homo- or copolymer; b) a bromine-containing flame retardant; c) a UV absorber; d) a sterically hindered amine and e) an epoxidized fatty acid. This invention also relates to the use of the light stabilizer mixture consisting of the components c), d) and e) for light-stabilizing a styrene, &agr;-methylstyrene or p-methylstyrene homo- or copolymer finished with a bromine-containing flame retardant as well as to a process for the light-stabilization thereof. Adding an epoxidized fatty acid to a UV absorber and a sterically hindered amine in styrene, &agr;-methylstyrene or p-methylstyrene homo- or copolymer finished with bromine-containing flame retardants results in an unexpected synergistic effect in the light stability. In particular, it is possible to markedly reduce the discoloration of the finished polymer which takes place in the course of irradiation.
