Polyvinyl chloride stabilized with sulfur dioxide complexes of alkaline earth metal phenates
Abstract
Abstract THIS INVENTION PROVIDES AN ALKALINE EARTH METAL COMPLEX FORMED BY THE REACTION OF ALKALINE EARTH METAL PHENATE WITH AN INORGANIC ACID ANHYDRIDE, IN THE ABSENCE OF WATER. THE COMPLEX IS FREE FROM ALKALINE EARTH METAL IN EXCESS OF THAT STOICHIOMETRICALLY REQUIRED TO FORM THE PHENATE AND IS FREE FROM THE SALT OF THE ALKALINE EARTH METAL AND THE INORGANIC ACID ANHYDRIDE. THE ALKALINE EARTH METAL PHENATE COMPLEX HAS A REDUCED ALKALINITY AS COMPARED TO THE ALKALINE EARTH METAL PHENATE. THIS INVENTION ALSO PROVIDES A POLYVINYL CHLORIDE RESIN STABLILIZERS: A PRISING THE ALKALINE EARTH METAL PHENATE COMPLEX PLUS ANY ONE, OR COMBINATION, OF THE FOLLOWING STABILIZERS: A POLYVALENT HEAVY METAL SALT OF AN ORGANIC CARBOXYLIC ACID HAVING FROM TWO TO ABOUT EIGHTEEN CARBON ATOMS, AN ORGANIC COMPOUND CONTAINING AT LEAST ONE EPOXY GROUP AND HAVING FROM 10 TO 150 CARBON ATOMS, AND/OR AN ORGANIC TRIPHOSPHITE. THE INVENTION ALSO PROVIDES A POLYVINYL CHLORIDE RESIN COMPOSITION CONTAINING A COMBINATION OF THE ALKALINE EARTH METAL PHENATE COMPLEX PLUS ONE OF THE THREE OTHER STABLILIZERS LISTED ABOVE.
