Abstract
Effects of the temperature, carbon monoxide content in a mixture with ethylene, molar ratio C2H5AlCl2:Ti(O-n-C4H9)(4), and pressure of the e thylene-CO mixture on the kinetics of monomer consumption in the cours e of the ethylene-CO copolymerization in n-heptane were determined. Th e structures and some properties of the final copolymers were studied. It was established that carbon monoxide exhibits lower reaction abili ty toward copolymerization than does ethylene. The molecular mass of t he ethylene-CO copolymer is lower than the mass of polyethylene obtain ed with the same catalytic system. IR spectroscopic data show evidence of a random structure of the copolymers.
