    摘要： ORGANIC PHOSPHITES ARE PROVIDED HAVING IN THE MOLECULE AT LEAST ONE POLYCARBOCYCLIC PHENOLIC GROUP FOR EACH PHOSPHITE GROUP, SUCH POLYCARBOCYCLIC PHENOLIC GROUP HAVING FROM ONE TO ABOUT THIRTY CARBON ATOMS PER PHENOLIC GROUP, AND HAVING THE FORMULA:

    (AR)P
    AND THE PHOSPHITE HAVING AT LEAST ONE ALIPHATIC AND/OR CYCLOALIPHATIC GROUP AND HAVING THE FORMULA:

    (AR)P
    WHICH IN POLYMERIC PHOSPHITES ARE LINKED TO ADDITIONAL PHOSPHITE GROUPS, SUCH PHOSPHITES CONTAINING AT LEAST ONE ALIPHATIC OR CYCLOALIPHATIC GROUP FOR EACH ONE TO TEN PHOSPHITE GROUPS; AND Y IS A LINKING NUCLEUS SELECTED FROM THE GROUP CONSISTING OF TRIVALENT, TETRAVALENT AND PENTAVALENT ALIPHATIC, CYCLOALIPHATIC, AND AROMATIC HYDROCARBON GROUPS, ATTACHED TO EACH AR GROUP THROUGH A CARBON ATOM NOT A MEMBER OF AN AROMATIC RING, AND SUCH ALIPHATIC RADICALS INCLUDING CARBOXYLIC ACID ESTER GROUPS, AND HAVING FROM ONE TO ABOUT THIRTY-THREE CARBON ATOMS.

    (HO)M-AR- AND (AR)P
    WHEREIN AR IS A CARBOCYCLIC AROMATIC NUCLEUS AND AT LEAST ONE AR NUCLEUS HAS A PHENOLIC HYDROXYL GROUP, M HAS A VALUE ONE TO ABOUT FIVE; P HAS A VALUE FROM TWO TO FOUR; AND Z IS TAKEN IN SUFFICIENT NUMBER TO SATISFY THE VALENCES OF THE TWO PHOSPHITE OXYGEN ATOMS, INCLUDES AT LEAST ONE ALIPHATIC OR CYCLOALIPHATIC GROUP; AND IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN; MONOVALENT AND BIVALENT ALIPHATIC, AROMATIC, AND CYCLOALIPHATIC HYDROCARBON RADICALS HAVING FROM ABOUT ONE TO ABOUT THIRTY CARBON ATOMS; AND MONOVALENT AND BIVALENT PHENOLIC GROUPS HAVING FROM ONE TO ABOUT THIRTY CARBON ATOMS PER PHENOLIC HYDROXYL GROUP, AN SELECTED FROM THE GROUP CONSISTING OF

    摘要： A POLYVINYL CHLORIDE RESIN STABILIZER IS PROVIDED HAVING A HIGH CONCENTRATION OF TIN, IN THE RANGE FROM ABOUT 18 TO ABOUT 35% BY WEIGHT, AND A HIGH CONCENTRATION OF SULFUR, WITHIN THE RANGE FROM ABOUT 10 TO ABOUT 25% SULFUR, COMPRISING AT LEAST ONE ORGANOTIN ALPH-OR BETAMERCAPTO CARBOXYLIC ACID ESTER SULFIDE, AND PREFERABLY MIXED MONOORGANOTIN AND DIORGANOTIN ALPHA- OR BETAMERCAPTO CARBOXYLIC ACID ESTER SULFIDES. POLYVINYL CHLORIDE RESIN COMPOSITIONS ARE ALSO PROVIDED, CONTAINING THESE STABILIZERS.
