摘要:
An anti-reflection material and a polarization film which exhibit superior anti-reflection properties by preventing external light such as sunlight, fluorescent light, etc., from being reflected on a display, which yield a clear image without sparkling and reduces image contrast, and which exhibit superior wear resistance, chemical resistance, and contamination resistance, as well as exhibit optical stability. A hard coat layer is provided on one surface or two surfaces of a transparent substrate directly or via another layer, and an anti-reflection film having a lower refraction index than the hard coat layer is further provide on the hard coat layer. The hard coat layer consists of at least {circle around (1)} a polymer polymerizing (metha)acrylate compound having a fluorene structure; {circle around (2)} a polymer polymerizing urethane (metha)acrylate compound and ultrafine particles having a high refraction index; and {circle around (3)} radiation and/or thermosetting resin and surface-treated titanium oxide ultrafine particles.

A base rubber selected from natural rubber and diene rubber is blended with, based on 100 parts by weight of the base rubber, 0.5 to 5 parts by weight of a 2,2,4-trimethyl-1,2-dihydroquinoline polymer having a primary amine content of not more than 1% by weight, a monomer content of not more than 3% by weight and a dimer content of at least 30% by weight. The resulting rubber composition is vulcanized in contact with a reinforcing material such as an organic fiber or a steel cord. The rubber article thus obtained and reinforced with the reinforcing material is excellent in adhesiveness between the rubber and the reinforcing material, and further in thermal resistance.

An adhesion promoter comprises a polymeric strand with an epoxy-reactive group other than a phenolic hydroxyl group, and a crosslinking group that crosslinks the polymeric strand with a rubber in a crosslinking reaction, wherein the polymeric strand is water soluble in an amount of at least 10 g/l, and more preferably at least 100 g/l. Particularly contemplated adhesion promoters may further comprise styrene-butadiene-vinylpyridine copolymer, and may advantageously be employed as a replacement for resorcinol-formaldehyde latex in the fabrication of a rubber containing tire. Especially contemplated rubber compositions may additionally comprise maleinized polybutadiene to synergistically improve adhesion of the rubber to a polymeric fiber coupled via contemplated adhesion promoters.

A curl-resistant, antislip abrasive backing which includes a polymer-reinforced paper having a first surface and a second surface; a synthetic polymeric layer bonded to the first surface; and an amorphous, rubbery polymer film layer bonded to the second surface. Also provided is a curl-resistant, antislip abrasive paper which includes a polymer-reinforced paper having a first surface and a second surface; a synthetic polymeric layer bonded to the first surface; a layer of abrasive particles bonded to the synthetic polymer layer; and an amorphous, rubbery polymer film layer bonded to the second surface. By way of examples, the amorphous, rubbery polymer may be a polyester elastomer or an amorphous, rubbery polypropylene.
摘要:
Unsaturated polyetherester resins, and processes for making them, are described which are useful for making curable thermoset resin compositions, intermediates for curable thermoset resin compositions, fiber-reinforced polymer composites, intermediates for making skin laminates for gel coated fiber-reinforced composites and gel coated polymer laminates. The unsaturated polyetherester resins are obtainable by reacting at least one acid-terminated unsaturated polyetherester resin with at least one aromatic polyol having at least one non-primary hydroxy group to produce an unsaturated polyetherester resin at least partially end-capped with an aromatic polyol. The described processes, compositions, methods and uses improve the chemical and/or water resistance of resin compositions, particularly composite materials having a gel coat. That improvement has special significance in outdoor and marine applications, bathtubs and shower stalls, and environments exposed to chemicals such as industrial and commercial applications.

The present invention relates to a shoe sole that includes a polyamide in the form of powder or microfibers admixed with a thermoplastic base material to improve the strength, durability, abrasion resistance, and other desirable physical properties of the shoe sole. Suitable thermoplastic base materials include rubber, polyurethane or ethylene vinyl acetate. The polyamide microfibers are randomly and nonuniformly oriented to reinforce the shoe sole in all directions.
摘要:
An encoder made of rubber material in which the S-poles and the N-poles are alternately magnetized in circumference, whose magnetic force is strong and whose variation of the magnetic force is slight in the circumferential direction when it is magnetized. And a manufacturing method thereof. A ring shaped rubber compound made of unvulcanized rubber material into which magnetic powders are mixed and having thickness t1 of 1.5 times to 5 times thicker than the thickness t of the encoder made of rubber material as the final product is vulcanizingly molded. In this vulcanizingly molding process, the thickness of ring shaped rubber compound is reduced to one fifth (⅕) to two thirds (⅔) by compressing the ring shaped rubber compound in the axial direction under high temperature. And then, vulcanizingly molded one is magnetized S-poles and N-poles alternately in circumference.
