发明名称 Process for producing polybutene-1.
摘要 <p>Disclosed is a process for producing polybutene-1 suitable to be molded into pipes and the like by vapor phase polymerization in the presence of a catalyst obtained from (A) a solid catalyst component obtained from a magnesium compound, an electron donating compound and a halide of tetravalent titanium (B) an organoaluminum compound and (C) an electron donor wherein said solid catalyst component (A) has an average particle size of 5-200 mu m, a geometrical standard deviation ( sigma g) of particle size distribution of less than 2.1 and a molar ratio of electron donating compound/magnesium of 0.01 or more and said electron donor (C) is at least one compound selected from the group consisting of a heterocyclic compound represented by the formula: &lt;CHEM&gt; (wherein R&lt;1&gt;, R&lt;2&gt;, R&lt;3&gt;, R&lt;4&gt; and R&lt;5&gt; are as defined before), an ether compound represented by the formula: R6_nC(OR&lt;7&gt;)4-n (2) (wherein R&lt;6&gt; and R&lt;7&gt; and n are as defined before) and an organic peroxide represented by the formula: &lt;CHEM&gt; (wherein R&lt;8&gt;, R&lt;9&gt;, R&lt;1&gt;&lt;0&gt; and R&lt;1&gt;&lt;1&gt; are as defined), and the vapor phase polymerization is carried out at a molar ratio of hydrogen/butene-1 of 0.001-0.1.</p>
