Assignee:

Ciba Specialty Chemicals Corp. - Tarrytown NY

International Classification:

C08K 53415

US Classification:

524 99, 524141, 524145, 524415, 524 91

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, cydoalkoxy 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.

International Classification:

C08K 534

US Classification:

524100, 524101, 524102, 524103, 524104, 524105, 524126, 524148, 524151

Abstract:

Hindered amine compounds containing a group of the formula where G and G are independently alkyl of 1 to 4 carbon atoms or are together pentamethylene, Z and Z are each methyl, or Z and Z together form a linking moiety which may additionally be substituted by an ester, ether, amide, amino, carboxy or urethane group, and E is alkoxy, cycloalkoxy, aralkoxy, aryloxy, âOâCOâOZ , âOâSi(Z ) , âOâPO(OZ ) or âOâCH âOZ where Z , Z , Z and Z are selected from the group consisting of hydrogen, an aliphatic, araliphatic and aromatic moiety, when added to a wide variety of polymeric substrates, particularly polyolefins and styrenic polymers, surprisingly bestow flame retardant properties to such compositions. 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.

International Classification:

C08K005/34

US Classification:

524100000

Abstract:

Polyolefin fibers and filaments, and fabrics made therefrom, are rendered dyeable via a combination of dyeability additives. The dyeability additive combination comprises at least one compound selected from the group consisting of the polyamides, copolyamides and polyetherpolyamides and at least one ethylene vinyl acetate. The dyed polyolefin fibers and fabrics are rendered light stable via the use of a combination of stabilizers, which comprises at least one compound selected from the group consisting of the ultraviolet light stabilizers and at least one compound selected from the group consisting of the hindered amine light stabilizers. The ultraviolet light stabilizers are for example hydroxyphenylbenzotriazoles or tris-aryl-s-triazines. The hindered amine light stabilizers are for example of high molecular weight, for instance greater than 1000 g/mol. The dyes are for example anthraquinone blue dyes, anthraquinone red dyes, diazo red dyes or nitro yellow dyes.
