    Abstract: THIS INVENTION IS DIRECTION TO A COMPOSITION COMPRISING A POLYMER AND A NOVEL STABILIZER OF THE FORMULA:

    2-(R2-O-),(R1)N1-1,3,2-BENZODIOXAPHOSPHOLE

    IN WHICH R2 IS SELECTED FROM THE GROUP CONSISTING OF ARYL AND SUBSTITUTED ARYL, R1 IS SELECTED FROM THE GROUP CONSISTING OF ALKYL, SUBSTITUTED ALKYL, ARYL AND SUBSTITUTED ARYL, AND N1 IS FROM 0 TO 4. WHERE N1 IS MORE THAN 1, THE SUBSTITUENTS R1 MAY BE THE SAME OR DIFFERENT. POLYMERS STABILIZED IN THE PRACTICE OF THIS INVENTION INCLUDE POLYETHYLENE, POLYPROPYLENE, ACRYLONITRILE-BUTADIENE-STYRENE COPOLYMERS AND POLYSTYRENE.

    Abstract: CYCLIC PHOSPHITES, SUCH AS PHENYL NEOPENTYL PHOSPHITE ARE PRODUCED BY REACTING PHENOL IN THE MELT WITH A CRUDE REACTIIION PRODUCT OF PCL3 AND A 2,2-DI-LOWER ALKYL-1,3-PROPANE GLYCOL AND RECOVERING THE DESIRED PRODUCT BY DISTILLATION. THE CYCLIC PHOSPHITES ARE USEFUL AS STABILIZERS FOR ORGANIC COMPOSITIONS SUCH AS RUBBER AND POLYVINYL CHLORIDE.
