Abstract
1297550 Organotin stabilizer for halopolymers M & T CHEMICALS Inc 16 Dec 1970 [17 Dec 1969] 59762/70 Heading C3P A heat-stabilizer for halogen-containing polymers comprises a mixture of (i) an organo-tin compound having one direct carbon-to-tin bond, one direct halogen (other than fluorine)-totin bond and two direct sulphur-to-tin bonds end (ii) a compound of formula R 2 Sn(SR<SP>1</SP>) 2 , wherein each of R and R<SP>1</SP> is alkyl, cycloalkyl, aryl, alkaryl or aralkyl, R<SP>1</SP> alternatively being a radical of formula -R<SP>8</SP>-COOR<SP>9</SP> where R<SP>8</SP> and R<SP>9</SP> are hydrocarbon groups. The polymer may be P.V.C. or polyvinylidene chloride, or copolymers of vinyl chloride or vinylidene chloride with other ethylenically unsaturated monomers such as vinyl acetate. The stabilizer (i) is preferably of the formula wherein R<SP>2</SP>, R<SP>3</SP>, R<SP>4</SP> and R<SP>7</SP> are hydrocarbon groups, R<SP>3</SP> and R<SP>4</SP> alternatively being radicals of formula -R<SP>5</SP>-COOR<SP>6</SP> where R<SP>5</SP> and R<SP>6</SP> are hydrocarbon groups, and X is Cl, Br or I.
