Abstract: It is an object of the invention to provide polypropylene adhesives which have excellent adhesion to polar materials and exhibit particularly excellent adhesion after high-speed cast film processing, stretching or extrusion coating, and are excellent in blushing resistance, and multilayer structures having the adhesives. The adhesive resin composition is a grafted resin composition comprising a polypropylene component (A), an ethylene/propylene/?-olefin copolymer component (B), an ethylene/?-olefin copolymer component (C), and an unsaturated carboxylic acid and/or a derivative thereof (D), and which contains the component (A) at 5 to 80 parts by mass, the component (B) at 5 to 70 parts by mass and the component (C) at 1 to 40 parts by mass based on 100 parts by mass of the components (A), (B) and (C) combined and has an ethylene/propylene/?-olefin ratio in n-decane-soluble components of 5-95/5-95/1-50 mol % and a graft ratio of 0.01 to 5 wt %.

Abstract: In a coextrusion molding method, a laminate having excellent interlaminar adhesion strength with a fluorocopolymer is provided, and also a laminate which can be used more than enough even at high temperatures or in applications where the laminate comes into contact with oil, gasoline or the like by controlling various properties of the adhesive layer is provided. The laminate of the present invention is a laminate of at least two or more layers comprising a structure obtained by bonding and laminating an adhesive (A) defined by the following (i) to (iii) and a fluorocopolymer (B), wherein the adhesive (A) (i) is obtained by allowing a polyolefin (a) having a group reactive with a carbodiimide group to react with a compound (b) having a carbodiimide group, (ii) has a ratio of peak intensity at 2130 to 2140 cm?1 to peak intensity at 1470 cm?1 of 60% or lower in infrared absorption spectroscopy, and (iii) has a density of 0.870 to 0.940 g/cm3.

Abstract: A 3-aminomethyltetrahydrofuran derivative is produced by preparing a 3-cyanotetrahydrofuran derivative in a high yield from a malic acid derivative, and reducing the cyano group of the 3-cyanotetrahydrofuran derivative. The process can produce the 3-cyanotetrahydrofuran derivative in a high yield from inexpensive industrial materials.
