A catalyst comprises a composition resulting from mutual contact of the following Components (A), (B), (C) and (D): said Component (A) being a reaction product resulting from mutual contact of components (a), (b) and (c); said component (a) being represented by the formula Me1R1p(OR2)qX14-p-q ..... I wherein R1 and R2 each are a C1-C24 hydrocarbon moieties, x1 is a hydrogen atom or a halogen atom, Me1 is titanium, zirconium or hafnium, p and q are 0 p 4, 0 q 4 and 0 p+q 4, said component (b) being represented by the formula Me2R3m(OR4)nX2z-m-n ..... II wherein R3 and R4 each are a C1-C24 hydrocarbon moieties, x2 is a hydrogen atom or a halogen atom, Me2 is an element of Groups I to III in the Periodic Table, z is a valence of Me2, and m and n are 0 m z, 0 n z and 0 < m + n z, and said component (c) being an organocyclic compound having two or more conjugated double bonds; said Component (B) being a modified organoaluminum compound having Al-O-Al bonds; said Component (C) being an organocyclic compound having two or more conjugated double bonds; and said Component (D) being an inorganic carrier or particulate polymer carrier. The disclosed catalyst find extensive use in the manufacture of olefinic polymers having a relatively high molecular weight and a relatively wide molecular weight distribution as well as olefinic copolymers having a relatively narrow composition distribution.
