Use of Bis-Adducts of Ethanedithiol With Alkyl- And Cycloalkyl Substituted Methylene Dioxolanes in the Composition of Polyvinyl Chloride

Abstract

By free radical addition of ethanedithiol to alkyl- and cycloalkyl-substituted methylene dioxolanes, the bis-adducts tested then as a plasticizer for PVC have been obtained. It has been established as a result of the carried out investigations that the introduction of the synthesized compounds into PVC composition improves the physical-mechanical properties, which has been connected with the availability of sulfur atoms, carbonyl groups and ether bond in the molecules of bis-adducts. The high operational indices from PVCplastics indicate good plasticizing properties of the synthesized bis-adducts, and therefore they can be recommended for practical use.
