Polyol esters of zinc mercaptoacids as heat stabilizers for PVC processing. |
摘要 |
<p>A zinc mercaptoacid ester of a polyhydric alcohol or ether, carboxylate, or ether-carboxylate thereof having at least one functional hydroxy group are improved heat stabilizers for halogen-containing polymer compositions. The phenomenon known as zinc burn during processing of such compositions is eliminated. Zinc bis-thioglycolates, zinc mercaptopropionates and zinc bis-mercaptosuccinates of glycols, glycerol, glycol ethers, glycol carboxylates, and glycerol carboxylates exemplify the new class of heat stabilizers.</p> |
