摘要: PROBLEM TO BE SOLVED: To obtain a catalyst composition containing a titanium compound and an alkali metal compound, capable of exhibiting an excellent effect in a low concentration and capable of being effectively used for the hydrogenation of a polymer containing ethylenic unsaturated bonds. SOLUTION: This catalyst composition contains at least (A) a titanium compound of the formula (A1 is a heterocyclic five-membered ring containing a heteroatomic phosphorus or nitrogen; A2 is A1 , cyclopentadienyl, etc.; L1 , L2 are each H, a halogen, a lower alkyl, phenyl, etc.), and (B) an alkali metal hydride itself or the alkali metal hydride prepared from an alkali metal- terminated living polymer in the polymer solution in situ. The molar ratio of the alkali metal: titanium is preferably at least 2:1. The employment of the catalyst composition enables to hydrogenate an olefinic unsaturated polymer in a state dissolved in a hydrocarbon solvent, and also to hydrogenate the polymer after polymerized in a hydrocarbon solvent.

摘要: PROBLEM TO BE SOLVED: To obtain a catalyst compsn. which is useful for hydrogenating an ethylenially unsatd. polymer, is active at a sufficiently low concn., and it not required to be removed from the resultant hydrogenated polymer by incorporating a specific Ti compd. and a specific alkali metal hydride into the same. SOLUTION: This compsn. contains a Ti compd. represented by formula I wherein A1 is an indenyl group represented by formula II [wherein R1 and R2 are each a halogen, (substd.) phenyl, a lower alkyl, a (phenyl)alkoxy, phenoxy, benzyl, or a bulky group having at least one hetero atom (e.g. a tri- lower-alkylsilyl or -NPh2 ); n is 0-4; and m is 0-3]; A2 is A1 or (substd.) cyclopentadienyl; and L1 and L2 are each H, a halogen, a lower alkyl, phenyl, phenyloxy, etc.}, and an alkali metal hydride (e.g. lithium hydride) which is added as such or synthesized in situ in a polymer soln. from an alkyli-metal- terminated living polymer and/or an alkyli metal alkyl further added.

摘要: PROBLEM TO BE SOLVED: To provide a catalyst which is more effective than a known catalysts, is stable, is active even when used in sufficiently low concentrations and is suitable for use in the hydrogenation of a polymer having ethylenic unsaturations by using a plurality of specified compounds. SOLUTION: This composition comprises a titanium compound represented by formula I, an alkali metal hydride which is initially added or produced in situ from an alkali-metal-terminated living polymer and/or an added alkyl alkali metal and hydrogen in the polymer solution, the molar ratio of the alkali metal to the titanium being at least 2:1, and a boron compound represented by formula II (wherein A1 and A2 are each cyclopentadienyl or indenyl; X1 and X2 are each H, a halogen, a lower alkyl, a lower alkoxyl or the like; and R1 , R2 and R3 are each a halogen, a lower alkyl, a lower alkoxyl or the like).
