POLYMERIC METAL DIALKARYLDITHIOPHOSPHATES ARE PRODUCED BY THE REACTION OF AN ALKYLENE-DI-P-PHENOL, PHOSPHORUS PENTASULFIDE, AND A GROUP II METAL COMPOUND. CALCIUM, BARIUM, AND ESPECIALLY ZINC ARE THE PREFERRED GROUP II METAL. THESE POLYMERIC MATERIALS SHOW EXCELLENT THERMAL STABILITY IN THE THERMOGRAVIMETRIC TEST. |
