Vinyl halide polymers stabilized with two organotin compounds
Abstract
Abstract THIS INVENTION RELATES TO IMPROVED TWO-COMPONENT STABILIZERS COMPRISING A COMPOUND OF THE FORMULA (RSNX1.5)N IN COMBINATION WITH A COMPOUND OF THE FORMULA R''2SNSR"2 AND TO HALOGEN-CONTAINING VINYL RESIN COMPOSITIONS STABILIZED AGAINST THE DETERIORATIVE EFFECT OF HEAT, SAID RESIN COMPOSITIONS CONTAINING EFFECTIVE AMOUNTS OF THE IMPROVED TWO COMPONENT STABILIZER. R IS A MONOVALENT ALKYL HYDROCARBON RADICAL CONTAINING BETWEEN 1 AND 4 CARBON ATOMS, INCLUSIVE; R'' IS A MONOVALENT ALKYL HYDROCARBON RADICAL CONTAINING BETWEEN 1 AND 12 CARBON ATOMS, INCLUSIVE; R" IS THE RESIDUE OF A CARBOXYLIC ACID ESTER, A BENZYL RADICAL OR A HYDROCARBON RADICAL SELECTED FROM THE SAME GROUP AS R'', X REPRESENTS SULFUR OR SPECIFIED OXYGEN-SULFUR MIXTURES AND N IS AN INTEGER BETWEEN ABOUT 2 AND 5.
