  • Publication number: 20040097620
    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.

  • Patent number: 6737469
    Abstract: The present invention is a method of incorporating a water insoluble organic chemical into a styrene-butadiene rubber latex dispersion and the resulting styrene-butadiene rubber latex dispersion. A styrene-butadiene rubber latex dispersion is provided comprising an aqueous phase and a disperse phase, with the disperse phase including particles of styrene-butadiene rubber. An organic solvent that is miscible in water and the water insoluble organic chemical are added together to the styrene-butadiene rubber latex dispersion. The addition of the water-miscible organic solvent allows the water insoluble organic chemical to pass from the aqueous phase into the disperse phase thus limiting separation of the water insoluble organic chemical from the latex dispersion. The resulting SBR latex has increased properties over conventional latices that use the same amount of the water insoluble organic chemical but that do not include the water-miscible organic solvent.

    Abstract: The invention provides a process for making a let-down of glass fiber reinforced composite comprising a polymer matrix and from 5 wt. % to about 60 wt. % of reinforcing fibers long fibers. The fibers are incorporated in the let-down as a concentrate of pultruded composite of substantially parallel fibers and thermoplastic polyamide where fiber length equals pellet length. The fibers in the let-down have improved dispersion and orientation in the final thermoplastic polymer matrix thereby providing substantially improved physical properties from the forming of the fiber reinforced pellet with a modified pellet polymer matrix. The long fibers are incorporated as a concentrate pellet in the final matrix polymer by mixing pellets with the final polymer compound in a heated extrusion mixing zone used to convey a composite melt into a shaping zone, whereby the mixing under heat and rotational shear disperses the long fiber-reinforced pellets into the let-down matrix polymer.

The coupling system comprises a polysulfurized alkoxysilane (“PSAS”) coupling agent (inorganic filler/diene elastomer) associated with a 1,2-dihydropyridine and a guanidine derivative. The present invention is further directed to tires and semi-finished products for tires comprising a rubber composition according to the invention. The invention is also directed to a coupling system (inorganic filler/diene elastomer) for a rubber composition based on a diene elastomer reinforced by an inorganic filler, where the coupling system comprises a polysulfurized alkoxysilane (PSAS) coupling agent in association with a 1,2-dihydropyridine and a guanidine derivative.

  • Publication number: 20030144391
    Abstract: An enhancer coating for enhancing the appearance of laminate material including a protective exterior coating is provided. The enhancer coating includes a number of components including a number of emulsion agents capable of adhering the enhancer coating to the protective coating on the laminate material. The coating also includes a number of gloss enhancing agents which increase the gloss level of the laminate material. Multiple coats of the enhancer coating can also be utilized to obscure, cover and/or repair minor scratches, abrasions or other defects on the laminate surface in order to further enhance the appearance of the laminate material.

  • Publication number: 20030130384
    Abstract: Polyolefins, especially polypropylene, can be made flame retardant by the incorporation therein of a synergistic mixture of a selected hindered amine substituted by an alkoxy, cycloalkoxy or hydroxyalkoxy moiety and a selected organic or inorganic brominated and/or phosphorus containing flame retardant, such as ammonium polyphosphate or decabromodiphenyl oxide wherein the amount of organic or inorganic flame retardant required to achieve an acceptable level of flame retardancy is significantly reduced compared to that needed when the hindered amine is not present.

  • Patent number: 6586507
    Abstract: Hindered amines substituted on the N-atom with an —O—E—OH moiety are particularly effective in stabilizing polyolefin and automotive coating compositions against the deleterious effects of oxidative, thermal and actinic radiation where the presence of the OH group on the compounds adds important properties not attainable by the use of normal —O—E moieties.

  • Patent number: 6583250
    Abstract: The bondability of a polyolefin, particularly to cyanoacrylate adhesives, is improved by incorporating in the polyolefin a polymerization initiator capable of initiating the polymerization of the monomers constituting the cyanoacrylate adhesive. The polymerization initiator may, for example, be a sterically hindered nitrogen base and may be mixed with the polyolefin at a temperature above the polyolefin's glass transition temperature using, for example, co-extrusion or co-injection methods.
