Enhanced Degradation Properties Of Polypropylene Integrated With Iron And Cobalt Stearates And Its Synthetic Application

Synthetic plastic leads to environmental contamination, and a promising solution to this problem is to use prooxidants as fillers within them to speed up the photooxidation and thermooxidation processes. This makes plastics more susceptible to biodegradation. In this study, the degradation propertie...
