## Abstract

Provided are organic antimony compound compositions comprising (a) at least one organic antimony compound having at least one antimony-sulfur-carbon (i.e. Sb-S-C) linkage and as a stabilizer therefor, (b) elemental sulfur. Also provided are stabilized organic polymer compositions comprising a halogen containing polymer and said organic antimony compound-elemental sulfur compositions.

## Claims

### Claim 1

A composition comprising
A. at least one organic antimony compound containing at least one antimony to sulfur to carbon linkage and being selected from compounds having the formulas: ##STR83## or the formula ##STR84## wherein R is selected from the group consisting of alkyl, aryl, cycloalkyl, cycloalkenyl, aralkyl, alkaryl, and alkenyl;
R.sup.1 is selected from the group consisting of alkyl, aryl, cycloalkyl, cycloalkenyl, aralkyl, alkaryl, alkenyl, ##STR85## R.sup.2 is hydrogen, alkyl, aryl, alkenyl, cycloalkyl or alkoxyalkyl; R.sup.3 is alkyl, aryl, cycloalkyl or alkenyl;
Y is selected from the group consisting of ##STR86## R.sup.4 is alkylene, arylene or alkenylene; R.sup.5 is a trivalent alkyl or aryl radical;
R.sup.6 is a tetravelent alkyl or aryl radical;
D is oxygen or sulfur;
i=1, 2 or 3;
j=1 or 2;
m=1 or 2 and m'=0 or 1;
n=1 or 2 and n'=0 or 1;
x is 0 or 1 with the proviso that when x=0 then m+m'=2 and n+n'=2, and when x=1 then m=1, m'=0, n=1 and n'=0;
z is 1, 2 or 3;
a is 2, 3 or 4;
q is 1, 2 or 3; and
p is 2, 3 or 4;
B. elemental sulfur in an amount from about 0.005% to about 2.0% by weight based on the weight of the organic antimony compound.

### Claim 2 (depends on 1)

The composition of claim 1 wherein the organic antimony compound is a compound according to formulas (I) or (II) wherein R.sup.1 is selected from C.sub.1 to C.sub.18 alkyl, phenyl, cyclohexyl, ##STR87## and i=2 or 3, m=2, n=2, x=0, q=1 or 2 and p=2 or 3.

### Claim 3 (depends on 1)

The composition of claim 1 wherein the organic antimony compound is a compound according to formula (I) wherein R.sup.1 is ##STR88## and i=3.
