摘要:
A composition including a polyarylether copolymer is provided. The copolymer includes a polyarylether backbone; and a sulfonated oligomeric group bonded to the polyarylether suitable for use as a cation conducting membrane. Method of bonding a sulfonated oligomeric group to the polyarylether backbone to form a polyarylether copolymer. The membrane may be formed from the polyarylether copolymer composition. The chain length of the sulfonated oligomeric group may be controlled to affect or control the ion conductivity of the membrane.

摘要:
Block copolyestercarbonates may be prepared by first conducting a reaction between at least one of resorcinol or an alkyl- or haloresorcinol and at least one aromatic dicarboxylic acid dichloride, preferably isophthaloyl dichloride, terephthaloyl dichloride or a mixture thereof, to produce a hydroxy-terminated polyester intermediate, and then conducting a reaction of the intermediate with a carbonate precursor, preferably in the presence of a dihydroxy compound such as bisphenol A. The products have excellent physical properties, including a high degree of weatherability. They may be blended with other polymers such as polycarbonates, poly(alkylene carboxylates), polyarylates, polyetherimides, and addition polymers to improve the weatherability thereof.
摘要:
Multilayer articles comprising a coating layer comprising resorcinol arylate chain members bound to a support substrate via an optional intermediate tie layer. Adhesion between the layers of the multilayer article is enhanced by modifying at least a part of a surface of at least one of the layers in the multilayer article by a technique selected from at least one of: surface adhesive treatment, surface corona treatment, flame treatment, plasma surface treatment, vacuum deposition treatment, ionization radiation, chemical surface treatment, surface abrasion treatment, and surface texturing treating.

摘要:
A silver multilayered film comprises at least one intermediate layer comprising a polymeric resin; a colorant composition and a flake composition, wherein the normal to the individual flakes are oriented at an average angle of about 0 to about 75 degrees with a normal to the multilayered film, and wherein the intermediate layer is located between a first layer and an second layer and further wherein the multilayered film has a lightness greater than or equal to about 60 and a change in lightness as a function of viewing angle of greater than or equal to about 40. A multilayered film comprises an intermediate layer disposed on and in intimate contact with a surface of a first layer and a second layer disposed on and intimate contact with a surface of the intermediate layer opposite the first layer, wherein the intermediate layer comprises a polymeric resin; a colorant composition and a flake composition, wherein the normal to the individual flakes are oriented at an average angle of about 0 to about 75 degrees with a normal to the multilayered film, and further wherein the multilayered film has a lightness greater than or equal to about 60 and a change of lightness as a function of viewing angle of greater than or equal to about 40.

The filter element includes: a first set of pleats, each pleat including a first tip radius and a first spacing; and a second set of pleats, each pleat including a second tip radius and a second spacing, wherein the first and second set of pleats are positioned upon a continuous filter media.
摘要:
A method of detecting a malware based on a white list comprises: receiving on a server side a program feature and/or a program behavior of a program to be detected sent from a client side; comparing the program feature and/or the program behavior of the detected program with legitimate program features and/or legitimate program behaviors stored in a white list; obtaining a legitimacy information of the unknown program based on the comparison result and feeding this back to the client side. In the invention, a legitimate program is determined by using a white list, thereby determining an illegitimate program excluded from the white list as a malware, which performs a determination and detecting and removing of a malware from another perspective.
