Abstract:
The invention provides protective articles comprising a backing that comprises a fluorinated polymer and a curable adhesive on at least one layer of the backing. The protective articles of the invention may be used to provide substrates or articles of the invention having a fluorinated surface. The invention also provides methods of preparing such articles, methods of repairing appliqués, and methods of edge sealing appliqués.
Abstract:
PROBLEM TO BE SOLVED: To provide a monomer, oligomer and polymer of aromatic sulfonic acid or phosphonic acid (or these derivatives), wherein the monomer, oligomer and polymer are obtained by an aromatic nucleophilic substitution using a sulfur or phosphorus nucleophilic reagent.SOLUTION: The monomer, oligomer and polymer of unfluorinated, partially-fluorinated or perfluorinated (perfluoro) sulfonic acid are produced by a reaction of an oligomeric or polymeric arene, which is halogenated and has low molecular weight, with (hydrogen) sulfite, dithionite, sulfide or other reducing sulfur salt while using a suitable oxidizing agent by the sulfur oxidation degree of less than +6 as much as possible to oxidize a sulfur-containing arene intermediate formed together with the formation of corresponding sulfonic acid functional groups (the groups of a sulfonic acid, sulfohalogenide, sulfonamide and sulfonic acid ester).
Abstract:
PROBLEM TO BE SOLVED: To provide a protective article that can be used for a coating surface and sealing of a surface edge of fluoropolymer applique, etc., adhered to a substrate using substantially all kinds of adhesives (for example, a pressure-sensitive adhesive, a thermosetting adhesive, and a hot-melt adhesive) or repair of the surface.SOLUTION: The protective article including a backing that includes a fluorinated polymer and a curable adhesive on at least one layer of the backing is provided. The protective article can be used for a substrate or to provide an article having a fluorinated surface. A method for manufacturing such an article, a method for repairing an applique, and a method for sealing the edge of the applique are also provided.

Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive composition from which a heat-, weather- and oil-resistant adhesive is obtained. SOLUTION: The adhesive composition contains component (A) and component (B). (A): A vinyl polymer having not less than two groups expressed by (A) general formula (1): -OC(O)C(R a )=CH 2 (wherein, R a is a hydrogen atom or a 1-20C organic group) in the molecule and not less than one group out of the groups expressed by general formula (1) at the molecular terminal. (B): A redox initiator. COPYRIGHT: (C)2007,JPO&INPIT
