摘要： Polyester molding compositions include an effective amount of a triazine-based antioxidant and a benzophenone ultraviolet light absorber sufficient to achieve a clor difference, as calculated in CIELab units under illuminant "D-65" according to ASTM Standard D-2244, of less than about 10,0, when exposed in a Xenon arc weather-ometer operated according to SAE J1885 for 315 Kj/sq.m. The triazine-based antioxidant is of the formula: ##STR1## wherein R is a phenolic group attached to the triazine ring via a C1 to C5 alkyl or an ester substituent. Preferably, the triazine-based antioxidant is 3,5-di-tert-butyl-4-hydroxyhydrocinnamic acid triester with 1,3,5-tris-(2-hydroxyethyl)-s-triazine-2,4,6-(1H, 3H, 5H) trione. The benzophenone UV-absorber is of the general formula: ##STR2## where R' is hydrogen or an alkyl radical.

摘要： A polymeric composition containing a polyacetal resin in conjunction with a formaldehyde inhibiting agent is described. The formaldehyde inhibiting agent comprises an aluminum pigment. The aluminum pigment may comprise elemental aluminum, such as aluminum flakes that cannot only drastically reduce formaldehyde emissions from the composition but can also give the composition a metallic appearance. In one embodiment, the aluminum pigment may be combined with the polyacetal resin in conjunction with an unhindered phenol and/or a polyethylene resin. In order to further reduce formaldehyde emissions, in one embodiment, a formaldehyde scavenger comprising a nitrogen containing compound can also be added.

摘要： A polyoxymethylene composition which exhibits improved stability against the degradative effects of ultraviolet light includes a triazine-based antioxidant and UV stabilizers. One preferred composition of the invention includes, based upon the total weight of the composition, an oxymethylene copolymer, between 0.015 to about 0.4 weight percent of 2,4,6-triamino-sym-triazine (as a formaldehyde scavenger), between about 0.25 to about 1.0 weight percent of each of 2-2(hydroxy-5-t-octylphenyl) benzotriazole, and bis(2,2,6,6-tetramethyl-4-piperidinyl)sebacate as UV light stabilizers, and between about 0.25 to about 1.0 weight percent of 3,5-di-tert-butyl-4-hydroxyhydrocinnamic acid triester with 1,3,5-tris(2-hydroxy-ethyl)-s-triazine-2,4,6-(1H, 3H, 5H)-trione as an antioxidant. Due to their enchanced UV-light stability property, the compositions of the invention find particular utility as molded automobile components.

摘要： Polymer compositions are described that contain at least two different immiscible phases for producing molded articles having a swirl-like or marble-like appearance. The first phase, for instance, may contain one or more polyoxymethylene polymers. The second phase, on the other hand, contains one or more polymers that together have a melting point that is from about 5° to about 30° different than the melting point of the polyoxymethylene polymer. In one embodiment, the second phase may contain a thermoplastic elastomer, a glycol-modified polyethylene terephthalate, or a polyamide and may have a melting point that is higher than the melting point of the polyoxymethylene polymer. The second phase is present in the polymer composition in relatively low amounts, such as in amounts less than about 5% by weight. The second phase can contain a high concentration of colorants that creates a contrast of colors when the molded article is produced.

摘要： A polymeric composition containing a polyacetal resin in conjunction with a blend of metal salts for reducing formaldehyde emissions. In one embodiment, the blend of metal salts comprises a metal salt of a fatty acid blended with a metal salt of a polycarboxylic acid. The metal salt of the fatty acid may comprise calcium propionate, while the metal salt of the polycarboxylic acid may comprise calcium citrate. The metal salts have been found to reduce formaldehyde emissions, especially when the composition contains a low gloss additive, such as acrylic polymer particles.

摘要： A thermoplastic copolyester composition that is able to maintain its color and mechanical strength after exposure to full weathering is provided. More specifically, a stabilizing system is employed in the composition that contains a mixture of one or more light stabilizers (e.g., hindered amines, UV absorbers, etc.), antioxidants (e.g., sterically hindered phenols, organophosphorous compounds, etc.), and secondary amines. By selectively controlling the type and concentration of the stabilizers, the present inventor has discovered that a composition may be formed that is generally resistant to color change and crazing (i.e., micro-crack formation) upon weathering. In addition to a stabilizing system, a processing stabilizer is also employed in the copolyester resin that includes a metal salt of a fatty acid having a chain length of greater than 22 carbon atoms. The present inventor has discovered that such stabilizers are particularly effective in reducing internal stresses during fiber or film formation and thereby minimizing brittleness of the resulting article. For example, a monofilament formed from the thermoplastic copolyester resin of the present invention may exhibit an elongation at break retention percentage of from about 85% to about 150% after exposure to a Xenon arc at 2000 kJ/m2 in accordance with Test Method SAE J1960.
