摘要:
A white board comprises a front surface layer composed of a polyester film having undergone a hard coat treatment and a rear surface layer composed of a sheet-like magnet. The white board can be easily attached to and detached from steel walls, glass plates, etc. and stored in a rolled state when not in use.
摘要:
A highly transparent film having high strength, suitable extensibility, high weather resistance, low moisture absorption and so on is disclosed, which consists mainly of EVAT. And also various laminates making the most of the above properties of the film are disclosed, which comprise the EVAT interposed between two inorganic material sheets, two organic material sheets, or an inorganic material sheet and an organic material sheet.
摘要:
A composite composed of vulcanized rubber and thermoplastic resin which adheres tightly to the rubber can be obtained by treating the surface of the vulcanized rubber with at least one of halogen, halogen generating compound and halogenoid, and bonding melted polyamide resin, polyester resin, styrene series resin or acrylic resin to the above treated rubber surface region by the injection or extrusion molding.
摘要:
A novel functional high polymeric substance having .alpha.,.beta.-unsaturated carboxylate group, which is obtained by reacting a liquid high polymeric substance containing carbon-to-carbon unsaturated double bond or a solution of said high polymeric substance with .alpha.,.beta.-unsaturated carboxylic acid and its derivative in the presence of pseudo halogen compound. A rubber composition suitable for sealant is obtained by compounding said functional high polymeric substance with a plasticizer and/or a filler.
摘要:
A high polymeric substance having isocyanate group is produced by reacting a liquid high polymeric substance containing carbon-to-carbon unsaturated double bond or a solution of said high polymeric substance with a cyanate, an alkyl hypohalite and an organic carboxylic acid.
摘要:
An impact-resisting anti-lacerative window glass unit or laminate of a sandwich structure is disclosed, which comprises two exterior plate-like member made of a transparent organic polymer (A) and a transparent organic polymer (B) or a transparent inorganic material, respectively, and multilayer structure intermediate films made of at least two kinds of polymers (C). The multilayer structure intermediate films are interposed between two exterior plate-like members. A method of fitting such an impact-resistsing anti-lacerative laminate to a window frame or an automobile is also disclosed, which comprises removing a fitting portion of a hard coated transparent organic polymer (A) and the multilayer structure intermediate films through peeling while remaining at least one layer of a high breaking strength material layer as one of at least two kinds of the polymers (C) in the multilayer structure intermediate films on a person's side, and fitting the laminate to the window frame or an automobile body with an adhesive sealant by utilizing a thus exposed surface.
摘要:
A vulcanized rubber composition containing at least 30% by weight, based on the amount of the rubber component, of syndiotactic-1,2-polybutadiene has a high adhesion, and can be easily and firmly adhered to another vulcanized rubber composition or to a porous material through a syndiotactic-1,2-polybutadiene thin film by a hot-melt adhesion process.
摘要:
A sandwich structure having an improved impact resistance comprises two outer plates and an intermediate layer interposed therebetween. The intermediate layer is comprised of plural films having a bonding force therebetween lower than that between intermediate layer and outer plate.
摘要:
An adhesive composition which shows improved stickiness and adhesive property at room temperature and exhibits an excellent adhering ability in a short time is prepared by compounding(a) an acrylonitrile-containing copolymer having carbon-to-carbon double bond(b) a phenol-polysulfide resin(c) a metal oxide, and(d) a polyfunctional electrophilic reactive compound containing at least two electrophilic reactive groups.
摘要:
A viscous rubber composition consisting mainly of a non-polar rubber, polybutene and white carbon has high adhesion and excellent puncture-sealing properties. Pneumatic tires provided with a puncture-sealing layer formed of such a viscous rubber composition have a high resistance against the puncture due to foreign substances penetrated through the tire.
