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 G, Ror Rcontains 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.

Benzotriazole/hals molecular combinations and compositions stabilized therewith

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.

Flame retardant compositions

The invention relates to thermoplastic polyolefin compositions having enhanced surface durability and products thereof which include a thermoplastic polyolefin base component at least one radiation-crosslinkable component present in an amount sufficient to enhance the surface durability of the thermoplastic polyolefin component when radiation-cured and at least one photoinitiator present in an amount sufficient to initiate crosslinking of the radiation-crosslinkable component upon exposure of the thermoplastic polyolefin composition to radiation. The invention further relates to methods of providing a cured thermoplastic polyolefin composition having enhanced surface durability by preparing a mixture having a thermoplastic polyolefin base component, at least one radiation-crosslinkable component in an amount sufficient to enhance the surface durability of the polyolefin when radiation cured, and at least one photoinitiator each in an amount sufficient to facilitate crosslinking of the radiation-crosslinkable component when a surface of the thermoplastic polyolefin composition is exposed to radiation, and then exposing the thermoplastic polyolefin composition to radiation in an amount sufficient to crosslink the radiation-crosslinkable component thereby providing a thermoplastic polyolefin composition having enhanced surface durability.

Polyolefin materials having enhanced surface durability and methods of making the same by exposure to radiation

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.

Carboxyl-terminated and hydroxyl-terminated aliphatic polyester compositions derived from 1,4-cyclohexane-dicarboxylic acid, and a glycol component comprising primarily of cycloaliphatic diols and modifying aliphatic glycols, said polyesters being optionally stabilized by the presence of ultraviolet light absorbing compounds and/or hindered amine light stabilizers and being used in powder coating formulations to provide improved weatherability thereto.

Weatherable powder coating compositions

Coating compositions containing a polyfunctional glycidyl ether of sorbitol cured at ambient temperature with polyamidoamine hardeners exhibit unexpectedly high resistance to loss of gloss when exposed to weathering conditions. The cured product also have good mechanical and chemical properties.

Method of coating with polyglycidyl ether of sorbitol and polyamidoamine

Advanced epoxy resins prepared by the reaction of diglycidyl ethers of di-secondary alcohols and dihydric phenols, said advanced resins being heat curable with suitable curing agents to afford cured coating compositions exhibiting a variety of excellent physical properties and performance characteristics.
