    • A process for producing a polyolefin having a terminal functional group in an industrially advantageous manner, comprising the step (A) of producing a terminally modified polyolefin of the general formula P-AlR R (wherein P represents a polymer chain, and R and R represent each a C1-C10 hydrocarbon group, etc.) in the presence of an olefin polymerization catalyst prepared from a solid titanium catalyst component (a), an organoaluminum compound (b), and optionally an organosilicon compound (c) and the step (B) of either conducting a substitution reaction between the -AlR R group of the polyolefin obtained in the step (A) and a compound having a functional structure, or conducting a substitution reaction between the -AlR R group of the polyolefin obtained in the step (A) and a compound having a structure capable of forming a functional group by solvolysis, followed by the solvolysis of the reaction product to yield a polyolefin of the general formula P-X (wherein P is as defined above, and X represents a functional group). The obtained polyolefin is useful as, for example, a compatibilizer for polymer blends and a starting material for molecular design.
