Abstract
Photooxidative degradation of ternary isotactic polypropylene (IPP)/epoxy m odified lignin (LER)/polypropylene grafted with glycidyl methacrylate (PP-g -GMA) blends has been studied. It has been established that at relatively h igh LER/IPP/PP-g-GMA concentration. photodegradable materials based on IPP/ epoxidized lignin can be obtained. This conclusion is supported by the resu lts of optical and electronic microscopy, surface and thermal properties an d IR- and UV-spectroscopy.
