ORGANIC THIOL METAL-FREE STABILIZERS AND PLASTICIZERS FOR HALOGEN-CONTAINING POLYMERS.

摘要

Organic thiol compounds including mercaptophenylcarboxylates are disclosed which can be utilized to plasticize and/or stabilize halogen- containing polymer compositions, especially polyvinyl chloride) compositions. Compounds of the present invention are utilized in polymers normally susceptible to deterioration and color change, which typically occurs during processing of the polymer or exposure to certain environments.
