<p>A process for preparing alkaline earth metal mercaptides in a two-step process, useful as synergists for organotin stablizers in halogen containing resins such as polyvinyl chloride, comprising: (1) reacting a metallic oxide or hydroxide of the metal desired in the final mercaptide; a magnesium aluminum or calcium alkoxide; and an alcohol to provide an alkoxide of the metal of the final mercaptan; and then (2) reacting the final alkoxide of (1) with a mercaptan to provide the desired metal mercaptide.</p> |
