1,3-Dicarbonyl compounds are provided having the formula:
wherein:
R1 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms, and
R2 is selected from the group consisting of hydrocarbon having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms;
R3 is selected from the group consisting of hydrogen, hydrocarbon groups having from one to about eighteen carbon atoms and such groups substituted with one or more groups selected from the group consisting of halogen, hydroxy, alkoxy OR1, ester COOR1, alkyl and alkoxycarbonyl alkyl having from one to about eighteen carbon atoms;
as well as metal and organotin enolate salts thereof.
The compounds are effective in enhancing the resistance to deterioration by heat and light of polyvinyl halide resins.
