Lifetime prediction of polymers requires accelerated ageing based on an increase in UV light intensity and temperature. However, the representativeness artificial is still issue. The relevance highly UV-induced weathering raises question reciprocity failure depending polymer. influences irradiance temperature photooxidation kinetics polyethylene were studied to determine extent which increasing...

some innovative solutions are proposed to the problem of the unavoidable physical migration of antioxidants from plastic films for packaging, in order to minimize the consequent undesirable effect of food contamination. in previous exploratory tests, phenolic antioxidant co-units were achieved and incorporated into polyethylene chain and now the work is extended to create new families of polyme...
