    摘要: PROBLEM TO BE SOLVED: To obtain the subject composition capable of exhibiting excellent adhesiveness to both a woven fabric and a soft film made of a polyolefin, useful in the field of packing of plastic base and a disposable article by including a specific conjugated diene polymer. SOLUTION: This composition comprises (A) a poly-1-butene polymer, (B) a tackifier resin and (C) 3-25 wt.% of a (semi)liquid (partially) hydrogenated conjugated diene polymer having =75 wt.% hydrogenation ratio). Preferably the composition has 20-60 wt.% of the component A, 30-75 wt.% of the component B, a fixed amount of the component C and (D) 0-5 wt.% of a stabilizer such as an antioxidant.

    摘要: PROBLEM TO BE SOLVED: To enhance reaction efficiency by providing a draft tube equipped with a window or a slot in a reactor and circulating a process fluid through the window or the slot by the rotation of the impeller in the tube. SOLUTION: A reactor 10 suitable in use of reaction such as polymn., crystallization or the like for a polycondensation polymer has a draft tube having a slot 18 formed thereto built therein and an impeller 14 is arranged in the draft tube 16. The impeller 14 is rotated by external power through a shaft 12 and a process fluid is forcibly directed downwardly within the draft tube 16. At this time, a part of the process fluid is taken out of an outlet 24 as a product but the greater part thereof is repelled from the bottom part 10a of the reactor 10 to upwardly flow through an annular part 19 provided with a barrier plate 20 and heated/cooled by a heat exchange coil 28 to be returned into the draft tube 16 through the slot 18.

    摘要: PROBLEM TO BE SOLVED: To obtain a soft rubberlike thermoplastic elastomer compsn. which strongly adheres to a rigid (polar) substrate such as a polycarbonate or ABS by compounding a hydrogenated elastomeric block copolymer having a specified structure with a plasticiazer, an olefin-acrylate polymer, and a polyolefin. SOLUTION: The hydrogenated elastomeric block copolymer has terminal resin blocks each formed from at least two kinds of monovinylarom. compd. and a central elastomer block formed from a conjugated diene. The compsn. pref. contains 15-60wt.% block copolymer, 15-45wt.% plasticizer, 5-20wt.% olefin- acrylate polymer (pref. an ethylene-acrylate polymer), and 0.1-20wt.% polyolefin (pref. polypropylene).
