    Abstract: PROBLEM TO BE SOLVED: To provide a metal complex usable as a gas adsorber having excellent gas-adsorbing characteristics, a gas-occluding material having a large effective occlusion capacity, and a gas-separating material having excellent gas-separating properties and a large adsorption capacity. SOLUTION: The metal complex comprises 2,5-dihydroxybenzoic acid, at least one kind of a metal selected from chromium, molybdenum, tungsten, manganese, iron, ruthenium, cobalt, rhodium, nickel, palladium, copper, zinc and cadmium, and a bidentate ligand (I) represented by general formula (I) (wherein, R 1 , R 2 , R 3 and R 4 are the same or different and each a hydrogen atom, an alkyl group which may have a substituent, or a halogen atom, or R 1 and R 2 , and R 3 and R 4 may form an alkylene group, an oxyalkylene group or an alkenylene group which may have a substituent in combination; n is 1 or 2; R 5 , R 6 , R 7 and R 8 are the same or different, and each a hydrogen atom, an alkyl group which may have a substituent, or a halogen atom, or R 5 and R 6 , and R 7 and R 8 may form an alkylene group, an oxyalkylene group or an alkenylene group in combination). The method for producing the metal complex is also provided. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide an industrially economically excellent production method of a modified polymer excellent in retention in polymer compositions and giving polymer compositions capable of retaining excellent weather resistance for a long term. SOLUTION: A modifier comprising a 4-alkoxysily alkoxy-2,2,6,6-tetraalkylpiperidine is reacted with a living polymer prepared by living anionic polymerization of a monomer comprising an aromatic vinyl compound or a conjugate diene compound to have 1,000-100,000 number-average molecular weight and, if required, a part of or the whole of conjugate diene units is hydrogenated.
