<p>A process for the preparation of olefin (co)polymers by the use of a specific catalyst, by which the molecular weights of the (co)polymers can be arbitrarily controlled by selecting the polymerization time or the average residence time in the polymerization tank; novel olefin (co)polymers excellent in rigidity, heat resistance and transparence, which are suitably usable for various industrial parts, containers, films, sheets, fibers and so on; moldings of the (co)polymers; and compositions containing the (co)polymers.</p> |
