Document Type and Number:
WIPO Patent Application WO1989005832
Kind Code:
A3
Abstract:
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 R<1> is cyano, carboxy, alkenyloxycarbonyl or an unsubstituted or substituted alkoxycarbonyl, cycloalkoxycarbonyl or aryloxycarbonyl radical; R<2> is one of the groups specified for R<1> or an unsubstituted or substituted aryl, carbamoyl, alkanoyl, cycloalkanoyl, aroyl, alkylsulfonyl, cycloalkylsulfonyl, arylsulfonyl or heterocyclic aryl radical; R<3> is hydrogen or an unsubstituted or substituted alkyl, cycloalkyl or aryl radical; R<4> 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.
