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.

Stabilized thermoplastic elastomer

This invention relates to copolymerizable ultraviolet light absorber monomers which are .alpha.,.beta.-unsaturated dicarboxylic half-esters of 2-hydroxy,alkoxy,methylolbenzophenone intermediate compounds. The monomers have the formula: ##STR1## where R is alkyl C.sub.1 -C.sub.8, and n is 1 or 2, and

Copolymerizable ultraviolet light absorber members which are .alpha.,.beta.

This invention relates to copolymerizable ultraviolet light monomers which are acrylate esters of 2-hydroxy, alkoxy, methylolbenzophenones having the formula: ##STR1## where R is alkyl C.sub.1 -C.sub.8,
