Behaviour of order of reaction and toughness of polypropylene at artificial thermal condition

Abstract

Polypropylene is accumulated in the environment that serious cause for society and human. It’s degradation under artificial climate was studied in this research. Polypropylene pieces (3*15cm ) were weighted and they were kept under artificial thermal condition for 0-12 hours at 80,100,120,140˚C temperature and weight were recorded at different time interval. Average weight loss of polypropylene samples were 0.3 – 0.4 % at end of 12 hours. The order of reaction (n) varies was obtained respect to degradation of polypropylene. The toughness of material was recorded, it varied from 35% to 95% from initial values.
