Abstract

Degradation of some copolymers of ethylene with Fischer-Tropsch derived olefins was investigated. Hydroperoxide and carbonyl formation in samples of ethylene copolymers with heptene-1, and ethylene multiple polymers with the Fischer-Tropsch derived 3,4 methyl-pentene and linear olefins were monitored by IR spectroscopy. The results correlated with results obtained from thermogravimetry, multiple extrusion and rheology in previous studies. It was shown that degradation of ethylene with Fischer-Tropsch derived olefins is related to the type of branch introduced into the chain by the copolymerization with the particular olefin.
