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 COORl, 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;
one R1 and R2 may be linked together as an alkylene group to form a cyclic or ring structure;
n is number from 1 to 3; and
Z is a polyvalent linking radical selected from the group consisting of a direct linkage between the groups; polyvalent hydrocarbon R3;
wherein:
R3 is a polyvalent hydrocarbon group having from one to about eighteen carbon atoms;
R4 and Rs are selected from the group consisting of hydrogen and hydrocarbon groups having from one to about eighteen carbon atoms; and R4 and R5 may be linked together as an alkylene to form a cyclic or ring structure;
X is -O- od -S-;
m is 0 or 1; and
R6 is selected from the group consisting of hydrogen, hydrocarbon having from one to about eighteen carbon atoms, and -R3-; 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.
