  Composition useful for molding into articles such as food containers, beverage bottles, cured structural plastics and the like comprising molding grade linear or unsaturated polyester or polycarbonate having reacted therewith or copolymerized therein the residue of one or more benzodioxylmethine compounds having the formula: wherein R¹ is cyano, carboxy, alkenyloxycarbonyl or an unsubstituted or substituted alkoxycarbonyl, cycloalkoxycarbonyl or aryloxycarbonyl radical; R² is one of the groups specified for R¹ or an unsubstituted or substituted aryl, carbamoyl, alkanoyl, cycloalkanoyl, aroyl, alkylsulfonyl, cycloalkylsulfonyl, arylsulfonyl or heterocyclic aryl radical; R³ is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical; R⁴ is hydrogen, alkyl, alkoxy, or halogen; n is 1 or 2; and X is an unsubstituted or substituted methylene or ethylene radical; provided the benzodioxolyl­methine compound bears at least one substituent that is reactive with one of the monomers from which the condensation polymer is derived, said benzodioxyl­methine residue absorbing radiation in the range of about 250 nm to 390 nm and being nonextractable from said polymer and stable under polymer processing conditions. The benzodioxylmethine residues are present in the polymer as an integral part of the polymer chain and absorb ultraviolet radiation in the range of about 250 to about 390 nm. The residues are non-­extractable from the polymer and stable at the conditions at which the polymers are manufactured and processed.

  可用于模塑食品容器、饮料瓶、固化结构塑料等物品的组合物，该组合物由模塑级线性或不饱和聚酯或聚碳酸酯组成，与之反应或共聚的一种或多种苯并二氧甲基化合物的残余物具有以下式子： 其中 R¹ 是氰基、羧基、烯氧羰基或未取代或取代的烷氧羰基、环烷氧羰基或芳氧羰基； R² 是 R¹ 所指的基团之一或未取代或取代的芳基、氨基甲酰基、烷酰基、环烷酰基、芳基、烷基磺酰基、环烷基磺酰基、芳基磺酰基或杂环芳基； R³ 是氢或未取代或取代的烷基、环烷基或芳基； R⁴ 是氢、烷基、烷氧基或卤素； n 是 1 或 2；以及 X 是未取代或取代的亚甲基或乙烯基；条件是苯并二氧代甲基化合物含有至少一个取代基，该取代基可与缩聚聚合物来源的单体之一反应，所述苯并二氧代甲基残基可吸收约 250 纳米至 390 纳米范围内的辐射，且不可从所述聚合物中提取，并在聚合物加工条件下保持稳定。 苯并二噁烷基甲烷残留物作为聚合物链的组成部分存在于聚合物中，可吸收约 250 纳米至约 390 纳米范围内的紫外线辐射。残留物无法从聚合物中提取，并且在聚合物生产和加工条件下保持稳定。
