Poly(vinyl chloride) (PVC) was loaded with various contents of Moringa oleifera (MO) leaves extract. The changes in the structure arising after loading MO into the polymeric matrix were monitored. In addition, their rheological and mechanical properties were investigated. Some thermal analyses techniques were performed to demonstrate any change in the thermal stability of PVC before and after adding MO. PVC/MO exhibited noticeable antibacterial efficiency when evaluated against Gram‐positive and Gram‐negative bacteria. A favorable antibacterial efficiency of PVC/MO boosted with increasing of MO content from 5% to 25% by weight when introduced into PVC. The photostability of PVC enriched with MO was investigated. The change in the rate of dehydrochlorination for PVC was detected. It was indicated with liberating HCl from the polymeric matrix.
