Composition of matter and method of preparing same, catalyst, method of producing the catalyst and polymerization process employing the catalyst

A method of producing a catalyst comprising forming a first catalyst component by reacting

• (A) a metal halide selected from the group consisting of metal dihalides and metal hydroxyhalide compounds of Group IIA and IIB, and
• (B) a transition metal compound wherein the transition metal is tatanium and the transition metal is bonded to at least one radial selected from the group consisting of hydrocarbyl oxides, imides, amides, and mercaptides;
• and
• reacting a solution of said first catalyst component with a second catalyst component selected from the group consisting of (a) organometallic compounds of Groups I, II, and III selected from the group consisting of lithium alkyls, Grignard reagents, dialkyl magnesium compounds, dialkyl zinc compounds, and hydrocarbyl aluminum halides;
• (b) metal halides and oxyhalides of metals of Groups IIIA, IVA, IVB, and VB;
• (c) hydrogen halides;
• and (d) organic acid halides selected from the group consisting of compounds having the formula ##STR2## wherein R"' is an alkyl, aryl, or cycloalkyl group or combination thereof and X is a halide;
• and then treating the solid product resulting from the combination of said first and second catalyst components with a titanium tetrahalide capable of enhancing the activity of said catalyst.
