Aminated PVC cross-linked with 2,2’-dichlorodiethyl ether as heavy metal absorber

Abstract

The paper describes the chemical modification of PVC consisting in the introduction of amino groups (1,4-dioxane, diethylenetriamine), and then cross-linking with dichlorodiethyl ether. The optimal extraction time was obtained for the polymer that had more chlorine atoms substituted with diethylenetriamine groups and ether. The obtained polymers were characterized by infrared spectroscopy (FTIR), elemental analysis (CHN) and differential thermal analysis (DTA).
