Abstract
PURPOSE: To obtain a polymer having a high melt viscosity and a high melt tension and, therefore, being suitable for inflation molding or blow molding, by polymerizing an olefin by use of a catalyst consisting of an organic Al catalytic component and a Ti catalytic component satisfying a specified requirement for bonding.
CONSTITUTION: A mutual reaction product, OR2/Ti (mol ratio) ≤0.25, is obtained by reacting (a) an organometallic bond-free Mg-containing component selected from the group consisting of (a1) a Mg compound containing a metal-bonded OR and/or R'OH (wherein R and R' are each a hydrocarbyl group) and having a mol ratio, (OR+R'OH)/Mg≥2, and (a1) a Mg compound prepared by reacting a1 with an R'OH-reactive reagent capable of reacting with the R'OH in a1, (b) a Ti-containing component and, if necessary, (c) a halogenating agent component. An olefin or olefins are (co)polymerized in the presence of[A]the mutual reaction product and[B]an organic Al compound. The ratio, OR2/Ti, can be greater than 0.25 when the product A formed from component (a) containing Al is solid and this product is further reacted with an organic Al halide.
