Hydroxy containing aromatic phosphites

Abstract

Abstract ORGANIC PHSOPHITES ARE PROVIDED HAVING IN THE MOLECULE AT LEAST ONE POLYCARBOCYLIC PHENOLIC GROUP FOR EACH PHOSPHITE GROUP, SUCH POLYCARBOCYCLIC GROUP HAVING FROM ONE TO ABOUT THIRTY CARBON ATOMS PER PHENOLIC GROUP, AND HAVING THE FOMULA AR(-OH)X-Y-AR(-OH)(M-X) AND THE PHOSPHITE HAVING THE FORMULA AR(-OH)X-Y-AR(-OH)(M-X)-O-P<(-O-Z-O-) WHEREIN AR IS A CARBOXYLIC NUCLEUS AND AT LEAST ONE AR NUCLEUS HAS A PHENOLIC HYDROXYL GROUP, M HAS A VALUE FROM ONE TO ABOUT FIVE; AND Z IS TAKEN IN SUFFICIENT NUMBER TO SATIFY THE VALENCES OF THE TWO PHOSPHITE OXYGEN ATOMS AND IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, MONOVALENT AND BIVALENT ORGANIC HYDROCARBON RADICALS HAVING FROM ABOUT ONE TO ABOUT TWENTYFOUR CARBON ATOMS, AND MONOVALENT AND BIVALENT PHENOLIC GROUPS HAVING FROM ONE TO ABOUT THIRTY CARBON ATOMS PER PHENOLIC HYDROXYL GROUP, AND SELECTED FROM THE GROUP CONSISTING OF (HO)M-AR AND AR(-OH)X-Y-AR(-OH)(M-X) WHICH IN POLYMERIC PHOSPHITES ARE LINKED TO ADDITIONAL PHOSPHITE GROUPS, SUCH POLYMERIC PHOSPHITES CONTAINING AT LEAST ONE ALKYL GROUP PER PHOSPHITE GROUP, AND Y IS A LINKING NUCLEUS SELECTED FROM THE GROUP CONSISTING OF OXYGEN, ALKYLENE, OXYALKYLENE, SULFOAKYLENE AND CYCLOHEXYLENE, THE ALKYLENE HAVING FROM ONE TO FIVE CARBON ATOMS.
