Abstract
A tetrafunctional epoxy resin was evaluated as a thermal stabiliser for use in PVC compounds. Its stabilising efficiency was tested by yellowness index, HCl liberation, UV absorption, induction time, and changes in the mechanical properties. It was demonstrated that epoxy resins with several epoxy groups are effective in stabilising PVC against dehydrochlorination during processing and use, compared with tribasic lead sulphate. 35 refs.
