ABSTRACT:
Organothiotin compounds with low tin content suitable as stabilizers for halogen containing resins e.g. polyvinyl chloride, are of formula ##EQU1## wherein R.sub.1 and R.sub. 2 are individually selected from the group consisting of alkyl radicals containing between 1 and 20 carbon atoms, cycloalkyl and phenyl radicals, m is an integer between 1 and 8, inclusive, and X and Y and individually selected from the group of radicals exhibiting the formulae ##EQU2## wherein Q.sub.1 represents a hydrogen atom, an alkyl radical containing between 1 and 6 carbon atoms, inclusive, or the radical CH.sub.2 Z.sub.3, wherein Z.sub.1, Z.sub.2 and Z.sub.3 are individually selected from the group of radicals exhibiting the formulae ##EQU3## and ##EQU4## or X and Y together form a divalent radical selected from the group consisting of ##EQU5## and ##EQU6## Q.sub.2 represents a divalent radical of a formula selected from the group consisting of ##EQU7## and wherein R.sub.3 is an alkyl radical containing between 1 and 20 carbon atoms or a substituted or unsubstituted phenyl or alkylphenyl radical, R.sub.4 is selected from the same group as R.sub.3, R.sub.5 is an alkyl radical containing between 1 and 20 carbon atoms, or a substituted or unsubstituted phenylalkyl radical wherein the alkyl portion of said phenylalkyl radical contains between 1 and 6 carbons atoms, R.sub.6 and R.sub.7 are selected from the same group as R.sub.3, R.sub.8 is selected from the same group as R.sub.5, R.sub.9 is a single bond, an alkylene radical containing between 1 and 20 carbon atoms, an alkylene radical containing between 2 and 20 carbon atoms or a substituted or unsubstituted phenylene radical, R.sub.10 is selected from the same group as R.sub.4, R.sub.11 is selected from the same group as R.sub.3, R.sub.12 is a single bond, an alkylene radical containing between 1 and 20 carbon atoms, an alkenylene radical containing between 2 and 20 carbon atoms or a substituted or unsubstituted phenylene radical, R.sub.13 is an alkylene radical containing between 1 and 20 carbon atoms or said alkylene radical substituted with at least one phenyl radical, an alkenylene radical containing between 2 and 20 carbon atoms, or a cycloalkylene radical containing 5 or 6 carbon atoms, R.sub.14 is an alkylene radical containing between 1 and 20 carbon atoms, and a, b, c, d, n and p are each selected from the integers 1 to 6, inclusive.
