<p>Process for Making Low Crystallinity Polyolefins Disclosed is a solution polymerization process for obtaining high yields of high molecular weight, low crystallinity polymers of propylene and higher 1-olefins at low catalyst levels. The polymerization is carried out using a catalyst system containing a soluble transition metal component derived from magnesium carboxylate and a salt of titanium, zirconium or hafnium, and specified alkyl aluminum halide activators.</p> |
