Abstract
A solid material which is a transition metal composition, or a support for a transition metal compound, is suspended in a liquid medium, the mixture is subjected to mechanical action and the treated mixture is spray-dried. If the solid is a support material, it is subsequently contacted with a transition metal compound. The mechanical action can be a grinding process or a process providing simultaneous vigorous agitation and a shearing action. The transition metal composition may be used with an organic metal compound to polymerize an unsaturated monomer to give a polymer of good particle form.
