Patent number: 7323502Abstract: 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 compound selected from the group consisting of the (a) sterically hindered nitroxyl stabilizers, (b) sterically hindered hydroxylamine stabilizers and (c) sterically hindered alkoxyamine stabilizers and (ii) at least one phosphazene flame retardant. Advantageously, a further flame retardant may be added, without the need of adding an antimony synergist. The compositions of the invention combine good flame retardant properties with light stability and good mechanical properties.Type: GrantFiled: February 27, 2003Date of Patent: January 29, 2008Assignee: Ciba Specialty Chemicals CorporationInventor: Nikolas Kaprinidis

Patent number: 7265171Abstract: The novel transparent polyolefin, polyester or polyamide article disclosed is stabilized against the effects of light, oxygen, heat and agressive chemicals by addition of 0.005-0.30% by weight the polymeric substrate of a hydroxyphenyl triazine UV absorber, and is characterized by its thickness between 1 and 500 ?m. Preferred polyolefin articles thus stabilized are agricultural films containing as further stabilizer a sterically hindered amine. The novel compositions act as selective UV filter especially useful in agriculture.Type: GrantFiled: February 22, 2006Date of Patent: September 4, 2007Assignee: Ciba Specialty Chemicals Corp.Inventors: David George Leppard, François Gugumus, Michela Bonora

Patent number: 7259198Abstract: The present invention provides polyolefin compositions that are UV stable and suitable for articles that may be exposed to sunlight. The present invention provides, in one aspect, a polyolefin homopolymer or copolymer comprising, by weight of the polyolefin: (a) from 0.001 to 2 wt % hindered amine; (b) from 0.001 to 1 wt % ethoxylated amine; and (c) from 0.001 to 1 wt phenolic antioxidant; wherein the amount of phenolic antioxidant (PA), ethoxylated amine (EA) and hindered amine (HA) present in the composition is satisfied by the equation: PA + EA HA = Q wherein Q ranges from 0.15 to 250 when each component is expressed as a weight percentage. The composition is stable towards UV radiation such that it is useful for any number of articles such as automotive components and other articles that are, for example, injection molded.Type: GrantFiled: June 11, 2003Date of Patent: August 21, 2007Assignee: ExxonMobil Chemical Patents Inc.Inventor: Daniel Vaillant
