Polyolefins/Lignosulfonates Blends. III. Photooxidation of Isotactic Polypropylene Epoxidized Lignsulfonates Blends

摘要

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