PROCESS FOR PRODUCTION OF SYNDIOTACTIC a-OLEFIN POLYMER
摘要
<p>Provided is a process by which a syndiotactic a-olefin polymer having a high racemic dyad fraction and a high molecular weight can be produced with excellent polymerization activity by means of a method that permits high-temperature polymerization. A process for the production of a syndiotactic a-olefin polymer by polymerizing a monomer component that comprises both at least one C3-10 a-olefin and a small amount of ethylene in the presence of an olefin polymerization catalyst which comprises (A) a transition metal compound represented by general formula [1] and (B) at least one compound selected from among (b-1) an organoaluminum oxy compound, (b-2) a compound that reacts with the transition metal compound (A) to form an ion pair, and (b-3) an organoaluminum compound, characterized by satisfying the relationship: 0.001 = PE/PO = 0.030 [wherein PE and PO represent respectively the molar amounts of ethylene and C3-10 a-olefin which are fed into a polymerizer under the condition of polymerization temperature of 25°C or higher].</p>
