Abstract: Blends of methyltin mercapto carboxylic acid esters and butyltin carboxylates which form homogeneous stable liquid mixtures and provide initial color control, processing heat stability, as well as light stability to chlorinated polymers are disclosed. As these compositions are homogeneous liquids at ambient temperatures they can be readily measured and mixed into the resins, and are thus easy to formulate, market and use.
