    摘要: Composition useful for molding into articles which 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 poly-methine compounds having the formula: ##STR1## wherein each R.sup.1 is independently selected from cyano, carboxy, alkenyloxycarbonyl, or a substituted or unsubstituted alkoxycarbonyl, cycloalkoxoycarbonyl or aryloxycarbonyl radical;each R.sup.2 is independently selected from one of the groups specified for R.sup.1 or an unsubstituted or substituted aryl, carbamoyl, alkanoyl, cycloalkanoyl, aroyl, alkylsulfonyl, cycloalkylsulfonyl, arylsulfonyl or aromatic, heterocyclic radical;each R.sup.3 is independently selected from hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical;A.sup.1 and A.sup.2 are independently selected from 1,4-phenylene radicals; andL is an organic linking group bonded by non-oxo carbon atoms to the oxygen atoms adjacent to L; provided the poly-methine compound bears at least one substituent that is reactive with one of the monomers from which the condensation polymer is derived.The polymethine 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.

    摘要: A composition useful for molding into articles such as food containers, soft drink bottles, cured structural plastics and the like, comprising molding grade linear or unsaturated polyester or polycarbonate having reacted or copolymerized therein a total of from 100 to about 800 ppm, of the residue of one or a mixture of methine reactants of the formula ##STR1## wherein R.sup.1 is hydrogen or an unsubstituted or substituted alkyl, alkenyl, cycloalkyl or aryl radical;A.sup.1 is an unsubstituted or substituted phenylene radical;A.sup.2 is an unsubstituted or substituted 1,4-phenylene radical;R.sup.2 is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical;R.sup.3 is cyano or ##STR2## and R.sup.4 is one of the substituents which R.sup.3 can represent or an unsubstituted or substituted carbamoyl, alkanoyl, aroyl, alkylsulfonyl, arylsulfonyl, aryl or aromatic heterocyclic radicals.The methine 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.
