The present invention relates to high purity monoalkyltin compounds, more specifically to alkyltin compound compositions containing monoalkyltin as major compound, and minor quantities of di- and/or trialkyltin compounds.
The present invention also relates to the preparation processes of such high purity monoalkyltin compounds, as well as to the uses of said monoalkyltin compounds as chlorine-containing polymer-stabilisers, glass coating chemicals and catalysts, as well as articles comprising at least one polymer matrix and a high purity monoalkyltin compound.
Disclosed is a method of producing a vinyl chloride resin which comprises subjecting a monomer selected from the group consisting of vinyl chloride and a monomer mixture containing vinyl chloride, as a major component, and at least one ethylenically unsaturated monomer copolymerized therewith as a minor component to polymerization reaction in the presence of
(a) a pentaerythritol or dipentaerythritol fatty acid ester or
(b) a pentaerythritol or dipentaerythritol fatty acid ester and a glycerol fatty acid ester.
