Abstract: The present invention provides a transparent sealant for organic EL element, which is excellent in flexibility and can seal the organic EL element sufficiently, and thus can suppress generation of dark spots thereby capable of enhancing visibility of an image when an organic EL display is produced. The transparent sealant for organic EL element 2 of the present invention is formed with a flexible polymer composition, and is disposed between the light emitting face of a light emitting element 3 and the sealing member 4 in an electroluminescence display panel 1 comprising the light emitting element 3 sequentially including a substrate 31, an anode layer 32, a light emitting layer 33 and a cathode layer 34, and a sealing member 4 disposed on the light emitting side of the light emitting element 3.

Abstract: The present invention provides an elastomer film which is excellent in transparency, mechanical strength, heat resistance and colorability and a producing method thereof. An elastomer material was obtained by kneading a polar-group modified olefin-based copolymer comprising derived from each monomer of ethylene, propylene and 8-methyl-8-carboxy-tetracyclo[4.4.0.12,5.17,10]-3-dodecene and tetra n-butoxyzirconium as a metal compound, granulating and palletizing. Then, an obtained pellet was subjected to press-molding to produce an elastomer film of the present invention, having an elastomer layer in which the above-mentioned polar group-modified olefin-based copolymer was crosslinked with a metal compound due to electrical interaction through a polar group in the above-mentioned polar group-modified olefin-based copolymer.

Abstract: The invention relates to a process and apparatus for producing a foamed body that allows simple control of the dimensions and gives foamed body with the desired dimensions in a stable manner. According to the invention, P2 is pressure at the point where pressure in the die begins to fall after casting a molding material containing no blowing agent into the die, ?P2 is the amount of reduction in pressure in the die from P2, P3 is the minimum pressure between the time of casting a molding material containing a blowing agent into the die completely cast and the time of beginning to increase the pressure in the die, ?P3 is the amount of increase in pressure in the die from P3, and ?P4 is the sum of ?P2 and ?P3.

Abstract: The names of a plurality of polyolefine resins are previously registered as index data in a name data base. An optimal operational pattern is stored in an operational pattern table for each combination of the name of a current resin under production and the name of a target resin to be produced. The optimal operation pattern is selected based on the name of the current resin under production and the name of the next target resin to be produced. Based on the selected optimal operational pattern, resin-type change control is executed.
