Patent

CA 1338333

The invention relates to a process for the preparation of a predominantly crystalline ethylene/propylen copolymer having less than 15 mol% of propylene units, which can be carried out in liquid propylene as the suspending agent, if metallocene catalyst components of the formulae I, II or III are employed and the partial pressures of ethylene and propylene have a specific ratio. Image (I), Image (II), Image (III), By means of this process, it is possible to increase the possible uses of polymerization plants which work with liquid propylene.
