  • Patent number: 7462670
    Abstract: Polymer substrates, for example ABS, PBT, PVC, PET, nylon 6, nylon 6?6, ABS/PBT, PC/ABS or ionomers, are made scratch resistant by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer and c) a primary or secondary fatty acid amide. The present polymers exhibit good weatherability, scratch resistance, good processability, good mechanical strength, good gloss retention and are non-sticky. The carboxylic acid reagent functionalized olefin polymer is for example maleic anhydride grafted polypropylene or polyethylene, or is a reaction product of maleic anhydride and an alpha-olefin, or is a tallow alcohol ester of said maleic anhydride products. The fatty acid amide is for example oleyl palmitamide or stearyl erucamide.

  • Patent number: 7419513
    Abstract: Compounds which have a benzotriazole and a hindered amine moiety in the same molecule are typified by the formula A wherein at least one of G2, R1 or R2 contains a hindered amine moiety are extremely effective light stabilizers having both the UV absorbing activity of a benzotriazole and the light stabilizing efficacy of a hindered amine in the same molecule. These compounds are effective stabilizers for thermoset resin compositions, thermoplastic resin compositions, for photographic applications, for pigmented or dyed polypropylene, polyamide or polyester fibers, and for white, dyed, dipped, unscented and/or scented candle wax against discoloration and fading when incorporated therein alone or in combination with an antioxidant.

  • Publication number: 20070066729
    Abstract: Coatings compositions, for example oil or water based coatings with alkyd, acrylic, acrylic alkyd, polyester, phenolic, melamine, epoxy or polyurethane resins, are made scratch resistant by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer and c) a primary or secondary fatty acid amide. The present coatings exhibit good weatherability, scratch resistance, good gloss retention and are non-sticky. The carboxylic acid reagent functionalized olefin polymer is for example maleic anhydride grafted polypropylene or polyethylene, or is a reaction product of maleic anhydride and an alpha-olefin, or is a tallow alcohol ester of said maleic anhydride products.

  • Publication number: 20060276571
    Abstract: Polyolefin substrates, for example polypropylene, polyethylene or thermoplastic olefin molded parts, are made scratch resistant and heat and light stable by the incorporation therein of an additive combination of b) a carboxylic acid reagent functionalized olefin polymer or copolymer, c) a primary or secondary fatty acid amide and d) a combination of a low molecular weight and a high molecular weight hindered amine light stabilizer. The present polyolefins exhibit good weatherability, scratch resistance, good processability, good mechanical strength, good gloss retention and are non-sticky. The carboxylic acid reagent functionalized olefin polymer is for example maleic anhydride grafted polypropylene or polyethylene, or is a reaction product of maleic anhydride and an alpha-olefin, or is a tallow alcohol ester of said maleic anhydride products. The fatty acid amide is for example oleyl palmitamide or stearyl erucamide.
