ABSTRACT:
A transition metal composition has the composition M.sub.m,X.sub.p,TYn'Z where M is a metal of Groups Ib, IIa, IIIb, VIIa or VIII of the Periodic Table, X is an anion, T is a transition metal of Groups IVA--VIA of the Periodic Table, Y is an anion, Z is a melt-producing compound, m' is greater than zero and less than 100, n' is greater than zero and less than 8 (m'+1), and p' is m' x(valency of M)/(valency of X). The compositions of this type may be transformed into a liquid by heating and the hot liquid sprayed and the spray cooled. The sprayed material has a useful particle form and may be used as a component of a polymerization catalyst to polymerize an unsaturated monomer such as ethylene.
