An electrical grade polyvinyl chloride resin composition suitable for use as an electrical insulation material and avoiding the use of lead based stabilizers having a high volume resistivity when exposed to or immersed in water and a high resistance to deterioration when heated at temperatures above 100.degree. C. is disclosed. The composition is composed of an electrical grade polyvinyl chloride resin, filler, carboxylic acid ester plasticizer, at least one heat stabilizer from which cadmium and lead are substantially excluded, and as a wet resistivity agent protecting against the effective of water, a defined amount of at least one alkaline earth metal oxide or hydroxide.

The polymerization of a monomer component that comprises vinyl chloride in an aqueous medium in the presence of a free radical generating polymerization initiator is terminated by introducing into the polymerization reaction mixture when from 70% to 95% of the monomer component has been polymerized from 0.01% to 0.10% by weight, based on the weight of the monomer component, of a chain-terminating agent that is an alkyl-substituted trisphenol, such as 1,1,3-tris(2-methyl-4-hydroxy-5-tert.butylphenyl)butane.

Organotin esters from acid esters of di or poly carboxylic acids are made by adding a base to a mixture of an organotin halide and the acid ester in the presence of water, and reacting to form the organotin ester, the amount of base and acid ester being to provide 0.9-1.3 equivalents and at least 0.9 equivalents respectively per g. atom of halogen in the organotin halide, and the conditions being such as not to cause substantial hydrolysis.
