摘要
The aim of this work is to search for innovative solutions to avoid physical migration of the stabilizers from plastic films. New families of macromolecular additives bearing tuned amounts of a selected functionality were explored, in particular, novel random copolymers of ethylene with 1-olefin co-units bearing an efficient antioxidant and/or anti-UV moiety covalently bonded to a mono- or disubstituted olefinic bond. Polyolefin blends containing the novel macromolecular additives showed higher degradation temperatures with respect to the neat matrix and its blends with 2,6-t-butyl-4-methoxyphenol (BHA). Aging tests showed that the novel antioxidants also constitute a protection against photo-oxidation.
