Abstract
Novel extracted natural stabilizer for the polymer was investigated in this study. The natural anti-aging was extracted from plants and it is demonstrated that this type of stabilizers are suitable for biodegradable polymers. Gynostemma pentaphyllum (0.01–0.03 wt%) were extracted and added to the poly(vinyl chloride) blend. The achieved polymeric films were exposed to an accelerated UV light aging process for 300 hours at ambient temperature. The efficiency of tested natural stabilizer was linked to blank PVC films. FTIR spectroscopy, weight loss, electronic microscope and scanning electron microscopy were performed. Using small amount of natural stabilizer is significantly beneficial because it does not influence the PVC properties.
