FT-IR spectrophotometric determination of the composition of ethylene—1-hexene copolymers

Polimery 2000, No 6, 405


DOI: dx.doi.org/10.14314/polimery.2000.405


Summary

The well-known FT-IR method used for the determination of composition of ethylene—α-olefin copolymers was modified to determine the composition of ultrahigh-M (~106) ethylene—1-hexene copolymers (Table 1). A relation (eqn. 8) derived to calculate the 1-hexene content in the copolymers uses the absorbance ratio evaluated after the analytical bands have been separated. The 722 cm-1 absorption bands should not be used in the present method of determination (Table 1).
