    Abstract: A process for the production of polyolefin hollow articles comprises charging the polyolefin with a stabilizer combination comprising (a) at least one compound from the group of the organic phosphites or phosphonites, (b) one or more compounds selected from the group consisting of i.) hydroxylamine derivatives and ii.) amine oxide derivatives and (c) at least one compound from the group of the hindered amine stabilizers, filling this mixture into a mold, heating this mold in an oven to above 280° C., such that the stabilized polyolefin fuses, rotating the mold around at least 2 axes, the plastic spreading to the walls, and cooling the mold while still rotating, opening it and taking the resultant hollow article out.

  • Publication number: 20040147649
    Abstract: A system and method for wood preservation comprises treating wood products via conventional pressure treating mechanics of sequential vacuum and pressure with a solution comprising an oligomeric, stoichiometrically balanced blend of primary and secondary diamines with modified diphenylmethane diisocyanates and a carrier solvent/reactant. Upon application, the carrier solvent/reactant evaporates, allowing polymerization of the remaining solution constituents to form a non-toxic, hydrophobic, elastomeric polyureathane linked copolymer that provides a long-term barrier against rot, environmental, termite and mold/fungus attack. Complete polymer impregnation of the wood's interstitial fiber space enables the hydrophobic property of the polymer to provide a long-time barrier to water penetration. Alternatively, the polymer may be surface applied to provide both protection and to prevent leaching out of CCA chemicals in the case of conventionally treated wood. The polymer is also an effective termiticide.

  • Publication number: 20040116563
    Abstract: The present invention provides a method for separating one or more selected polymer(s) from a mixture of polymers, as well as the recycled solid polymer product produced by the present method of the invention. One method of the present invention involves dissolving a mixture of polymers in a solvent to produce a solution, then cooling the solution to a temperature at which at least one of the selected polymers precipitates in the form of a solid. The solid is then separated from the suspension before being washed in a solvent at a temperature that is higher than the dissolving temperature, in order to produce a washed solid. The washed solid is separated from the second solvent. In one variant of the method, the suspension produced in the cooling step is treated with an added solvent.

    Abstract: Organic polymeric substrates, for example polyolefins such as polypropylene, can be made flame retardant by the incorporation of a synergistic mixture of (i) at least one sterically hindered amine stabilizer, (ii) at least one conventional flame retardant selected from the group consisting of the organohalogen, phosphorus containing, isocyanurate and melamine based flame retardants and (iii) at least one acid scavenger. The compositions of the invention combine good flame retardant properties with light stability and good mechanical properties. Polyolefin molded articles are stabilized against light, heat and oxygen and made flame retardant with the incorporation of at least one sterically hindered amine and at least one conventional flame retardant, while allowing normally high levels of flame-retardant fillers to be greatly reduced or eliminated.
