Effect of morphology on the photooxidation of polypropylene films
Photooxidative degradation of polypropylene films with different morphology (degree of crystallinity and orientation) has been followed by means of mechanical tests. The kinetics of the photooxidation are significantly depressed on increasing crystallinity and especially orientation.
This behaviour has been interpreted in terms of the reinforcing action due to the oriented crystalline fibrils.
A correlation has been attempted between the photooxidative kinetics and a morphological parameter.
