Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition and a pressure-sensitive adhesive sheet which does not cause the problems that when a semiconductor material is tacked to the adhesive sheet and diced into chips, it does not inordinately scatter the semiconductor material debris, does not cause scraping up of the adhesive and when it pick up the chiped semiconductor material after dicing, it does not generate static. SOLUTION: The pressure-sensitive adhesive composition contains 100 mass pts. elastomer and 0.1-30 mass pts. (meth)acrylate-amine copolymer. The elastomer is a copolymer copolymerized with at least one kind of halogen-containing monomer. The mass% of 0.1-55 of the elastomer is the halogen-containing monomer. The (meth)acrylate-amine copolymer is obtained by copolymerizing a (meth)acrylate monomer and an amine-containing monomer. The mass% of 0.1-30 of the (meth)acrylate-amine copolymer is the amine-containing monomer. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To solve problems such that a conventional adhesive tape does not have adhesive power corresponding to the recent micrifying of chip size, there is an attachment of paste on a diced chip, also a semiconductor member is destroyed by static electricity generated on peeling at the pick up time after dicing the semiconductor member and so on. SOLUTION: This adhesive composition having 100 pts. mass elastomer and 0.01-30 pts. mass amine curing agent having at least ≥2 functional groups is provided with that the elastomer is obtained by copolymerizing at least 1 kind of a halogen-containing polymerizable monomer and the content of the halogen-containing monomer is 0.1-55 mass % based on the total of the elastomer.

Abstract:
PROBLEM TO BE SOLVED: To provide a film/electrode structure and its manufacturing method equipped with an adhesive support layer which does not peel off from a solid polymer film even under a high-temperature and high-humidity environment during the operation of a fuel cell. SOLUTION: The solid polymer electrolyte film 2 is pinched by catalyst layers 3, 4 positioned at its inner periphery side with one of its faces coated with the catalyst layers 3, 4 and the adhesive support layer 9. The adhesive support layer 9 is made of an adhesive having fluorine atoms in its molecular structure. The adhesive is endowed with a tensile break elongation of 150% or more after curing. The film is also provided with porous diffusion layers 5, 6 coating the catalyst layers 3, 4 and the adhesive support layer 9, and the adhesive support layer 9 is integrated with the diffusion layer 6 by an adhesive permeation layer 10. Concaves and convexes with maximum heights within a range of 3 to 20 μm are formed at a part coated by the adhesive support layer 9 of the solid polymer electrolyte film 2, and the adhesive support layer 9 is pressed and joined by heating to the part where the concaves and the convexes are formed.

Abstract:
A fluoropolymer surface can be adhered to another surface by coating a fluoropolymer surface with a perfluorinated cycloalkane or a solution of a fluoropolymer in a perfluorinated cycloalkane to make a coated fluoropolymer surface, contacting said coated fluoropolymer surface with another surface, and then applying pressure to force said coated fluoropolymer surface and said another surface together, to adhere said fluoropolymer surface to said another surface. The process is carried out at a temperature below the perfluorinated cycloalkane's atmospheric pressure boiling point of 140 DEG C or more.
