Abstract: 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.

Abstract: Elastomeric compositions having resistance to hot grease aging are made from a blend of a thermoplastic copolyester elastomer, and chorinated polyethylene with or without the addition of a carbodiimide and a guanidine.

Abstract: Segmented thermoplastic copolyester elastomers containing recurring polymeric long chain ester units derived from phthalic acids and long chain glycols and short chain ester units derived from phthalic acids and 1,4-butanediol or 1,4-butenediol. The elastomers also contain polyvinylpyrrolidone and preferably also contain guanidine stabilizer, phosphorus stabilizer and diphenylamine.

Abstract: A siding panel and siding panel assembly. Each panel has a pair of ridges near the top edge so that the top edge of the panel can be nailed to a substrate while remaining spaced therefrom. The bottom edge of each panel is provided with a flange terminating in an inverted U-shaped opening adapted to engage the upper edge of an adjacent panel.
