NOVEL METHINE COMPOUNDS, POLYMERS CONTAINING THEM AND FORMED ARTICLES THEREFROM
Document Type and Number:
WIPO Patent Application WO1989010349
Kind Code:
A3
Abstract:
A composition useful for incorporation into polymer compositions employed for food packaging or the like comprising a bis- or tris-methine compound having the structural formula wherein A is selected from the radicals +TR wherein R' and R'' are each selected from chlorine, bromine, fluorine, alkyl, alkoxy, aryl, aryloxy and arylthio; each n is independently 0, 1, 2; R1 is selected from a large variety of radicals such as cycloalkyl, phenyl, and straight or branched alkyl which may be substituted; R2 is alkylene or the like; R3, R4, and R5 are each selected from hydrogen and alkyl; and P and Q and P1 and Q1 are selected from cyano, carbalkoxy, carbaryloxy, carbaralkyloxy, or the like. The invention compositions are especially useful in combination with molding or fiber-grade condensation polymer; most preferably such polymer having copolymerized therein a total of from 1.0 to about 100,000 ppm, of the reactant residue moieties of one or more of such bis- or tris-methine compounds.
