Heat stabilizers for polyvinyl chloride and similar polymers |
| abstract |
POLYMERS AND COPLYMERS OF VINYL CHLORIDE CAN BE THERMALLY STABILIZED BY ADDING AN ARYL ALKYL PHOSPHITE TOGETHER WITH A ZINC SALT IN AN AMOUNT CORRESPONDING TO BETWEEN 0.0005 AND 0.005 PART OF DIVALENT ZINC. IN THESE AMOUNTS, ZINC EFFECTIVELY RETARDS THERMAL DISCOLORATION WITHOUT CAUSING SUDDEN DEGRADATION. THE STABILIZED POLYMER COMPOSITIONS MAY ALSO CONTAIN OTHER CONVENTIONAL PLASTICS ADDITIVES. |
