机译:增强PVC组合物的热稳定化过程

摘要

ABSTRACT OF THE DISCLOSURE: The invention relates to stabilizer compositions for polymers based on polyvinyl chloride which comprises: a) at least one organic derivative of zinc, b) at least one derivative an organic metal of Group 2a of the Periodic Table, c) at least one polyol, and d) at least one ester of thioglycolic acid. It also relates to polymers based process for stabilizing polyvinyl chloride by such stabilizing compositions and stabilized poly-mers obtained. From polymers and bilisés sta-shaped objects are obtained colorless and trans-parents.
