The compositions of ethylene-propylene copolymers prepared in this work were determined by in'frared spectroscopy. Atactie polypropylene with head-to-tail linking
2
5-dimethylhexane
squalane and tetradecane were used as model compounds to determine the sequence distribution of ethylene-propylene copolymers according to the method used by Bucci et al.. The effects of various catalyst systems
with or without organic compounds as activators
on the sequence distribution of ethylene-propylene copolymers have been discussed.
