Propanediol-derived polyesters as PVC plasticizers

An overbased mixture of aliphatic and aromatic carboxylates salts useful in making low-fogging thermal stabilizers for PVC is made by reacting zinc oxide with fatty acid and such as stearic acid, then adding aromatic acids, and then adding and reacting one or both of magnesium oxide and calcium oxide, under controlled heating conditions to maintain fluidity while minimizing side reactions, and then conditioning the reaction product to remove volatiles.

Liquid polyvinyl chloride resin stabilizer systems are provided, based on complexes of organic triphosphites with zinc chloride, and, in addition, other compatible polyvinyl chloride resin stabilizers, including particularly, thiophosphites of mercaptocarboxylic acid esters, as well as barium-cadmium and barium-zinc carboxylic acid salt combinations, and liquid barium carbonate-alkyl phenate complexes.

Novel peroxydicarbonates are provided in which the alkyl carbonate moiety is 2-alkyl-2-phenyl substituted. The compounds are useful as polymerization initiators of ethylenically unsaturated monomers, such a vinyl chloride, and as catalysts of unsaturated polyester resins. The subject peroxydicarbonates are characterized in that they are solid at room temperature, have ambient temperature stability in spite of a low 10 hour half-life temperature, and can normally be transported and stored without refrigeration.
