The compound [tris(dimethylamino)phosphonioamino]tris[tris(dimethylamino)phosphoranylideneamino]phosphonium dichloride can be prepared by contacting hydrogen chloride with tetrakis[tris(dimethylamino)phosphoranylideneamino]phosphonium chloride. The phosphonium dichloride compound can be used in a process wherein it is brought into contact with an OH−-form ion exchange resin to prepare tetrakis[tris(dimethylamino)phosphoranylideneamino]phosphonium hydroxide. Separate processes for separating or isolating the phosphonium chloride compound or isolating the phosphonium hydroxide compound from feed solutions wherein an extraction step is used are also set forth.
摘要:
The present invention provides a process for producing an α-olefin polymer comprising polymerizing or copolymerizing (a) C3 or higher α-olefin(s) in the presence of an olefin polymerization catalyst comprising solid titanium catalyst component (I) containing titanium, magnesium, halogen, and a compound with a specific structure having two or more ether linkages and organometallic catalyst component (II) with high catalytic activity. In this process, particularly even in (co)polymerizing (a) higher olefin(s), demineralization is unnecessary. A 4-methyl-1-pentene-based polymer obtained by polymerization using the catalyst of the present invention is excellent in tacticity, transparency, heat resistance, and releasability, and the polymer is particularly suitable for a release film.
