M of M(OR1)z is a non-reducing transition metal other than titanium, the non-reducing transition metal being in an oxidation state of +2 or +3. Each R1 is independently (C1-C30)hydrocarbyl or —C(O)R11, where R11 is (C1-C30)hydrocarbyl. Subscript z of M(OR1)z is 2 or 3. Each R1 and R11 may be optionally substituted with one or more than one halogen atoms, or one or more than one —Si(RS)3, where each RS is (C1-C30)hydrocarbyl. A of A(Cl)x(R2)3-x is aluminum or boron; R2 is (C1-C30)hydrocarbyl; and x is 1, 2, or 3; and a magnesium chloride component.
