ABSTRACT:
Organotin compounds with low tin content suitable as stabilizers for halogen containing resins e.g. polyvinyl chloride are of formula ##EQU1## where R.sub.1 and R.sub.2 are C.sub.1.sub.-20 alkyl, cycloalkyl or phenyl, Q.sub.1 is of formula --C(CH.sub.2 Z).sub.2 Q.sub.2, wherein Q.sub.2 is H, C.sub.1.sub.-6 alkyl or CH.sub.2 Z, and each Z is ##EQU2## or a pair of Z is ##EQU3## R.sub.3 is C.sub.1.sub.-20 alkyl, optionally substituted phenyl, or alkylphenyl or if two R.sub.3 groups are present in the molecule, they may constitute a single bond between the carbon atoms immediately adjacent to said R.sub.3 radicals, C.sub.1.sub.-20 alkylene C.sub.2.sub.-20 alkenylene or optionally substituted phenylene, R.sub.4 is C.sub.1.sub.-20 alkyl, optionally substituted phenyl (C.sub.1.sub.-6) alkyl or two groups R.sub.4 are optionally phenyl substituted C.sub.1.sub.-20 alkylene or C.sub.2.sub.-20 alkenylene or C.sub.5.sub.-6 cycloalkylene R.sub.5 is C.sub.1.sub.-20 alkyl, optionally substituted phenyl or alkylphenyl or if two R.sub.5 groups are present, these may be bonded together to form a C.sub.1.sub.-20 alkylene radical or a substituted phenylene radical, R.sub.6 is a single bond, C.sub.1.sub.-20 alkylene, or C.sub.2.sub.-20 alkeynylene, n alkenylene, 1-6 and Y is ##EQU4## or Y and OCOCH = CHOOCH.sub.2 Q.sub.1 are together (OCOCH = CHCOOCH.sub.2).sub.2 C(CH.sub.2 Z)Q.sub.2.
