摘要： PROBLEM TO BE SOLVED: To obtain a resin composition having nondrippiness without detriment to mechanical properties, heat stability and surface gloss by mixing a styrene resin with a bromine-containing flame retardant, antimony trioxide and a multi- component copolymer having a specified compositional ratio. SOLUTION: This composition comprises 100 pts.wt. styrene resin, 10-30 pts.wt. bromine-containing flame retardant, 3-10 pts.wt. antimony trioxide and 0.3-12 pts.wt. multi-component copolymer having a composition of 5-99.5 wt.% epichlorohydrin, 94.5-0 mol.% ethylene oxide and 0.5-10 mol.% allyl glycidyl ether. The styrene resin is based on a homopolymer of styrene or a styrene derivative such as α-methylstyrene, vinyltoluene or chlorostyrene or a copolymer thereof with other monomers. The bromine-containing flame retardant used is decabromodiphenyl oxide or the like. The multi-component copolymer is prepared by copolymerizing the monomers in the presence of a catalyst such as an organoaluminum compound.

摘要： PURPOSE:To provide wear resistance, flection resistance, and resistance to wrinkles, and to obtain a rigid fixation surface which has good surface glossiness and superior contamination resistance by carrying out a heat treatment at 160-250 deg.C for 5-30sec after forming an image on the surface of a body to be printed when a copy is taken by using toner. CONSTITUTION:For example, a normal constant-temperature heater, a heat roll, or infrared-ray heater with a reflecting plate is provided as a fixation processing means and copied printed matter is passed through a heating atmosphere. This method is applicable similarly to a polyethylene chloride sheet, sheet containing polyethylene chloride, or specified copying form and a sufficiently stable print image is obtained. Then the fixation processing temperature is 160-250 deg.C and the time is short or 5-30sec. In general, the time is preferably 5-20sec almost is 180 deg.C. Consequently, there is not the possibility of the contamination of a print part due to the sticking of other printed matter, not to mention the bleeding and desorption of a copy image, and the stable printed matter which can be stored permanently is obtained.

摘要： PURPOSE:To produce a solvent-soluble low-molecular weight chlorinated polyolefin without using any organohalogen compound solvent. CONSTITUTION:A polyolefin having an average mol.wt. of 800-12,000 and a melt viscosity at 170 deg.C of 4,000 cP or lower is dispersed into an aqueous medium at a temp. higher than the melting point of the polyolefin by at least 5 deg.C, and the dispersed polyolefin melt is chlorinated until the combined chlorine content reaches 55-63wt.%. The chlorinated polyolefin is then reduced into smaller particles at a temp. not above the melting point, during which chlorination may be further conducted to a combined chlorine content of 60-72wt.%. By thus conducting the high-temp. chlorination in an aqueous medium and performing the particle reduction during the chlorination, a homogeneously chlorinated polyolefin excellent in solvent solubility is obtained.

摘要： PURPOSE:To improve moisture permeability, weather resistance, cold resistance and abrasion resistance by laminating a composition mainly comprising a two-dimensional or three-dimensional copolymer rubber using propylene oxide, ethylene oxide and aryl glicidyl ether as ingredients onto a fabric base and heating and vulcanizing the composition. CONSTITUTION:A composition mainly comprising a two-dimensional or three- dimensional copolymer rubber, in which propylene oxide, ethylene oxide and aryl glycidyl ether are contained respectively at 50-99mol%, 40-0mol% and 10-1mol%, is laminated onto one surface of a fabric base, and heated and vulcanized. A fibrous fabric base is employed normally as the fabric base laminated onto the rubber composition. A natural organic fiber and an inorganic fiber such as glass fiber, asbestos fiber, etc., are used as a fiber. A rubberized fabric having such constitution can be used in a wide field as the component of various bags, a flexible container, waterproof clothing, a tent, a belt, a hood for a truck, a sheet for an open freighting article, etc.

摘要： PURPOSE:To enable favorable printing to be performed by various printing methods without need for a pretreatment, by using a specified chlorinated polyethylene. CONSTITUTION:A chlorinated polyethylene to be used for a plastic-made printing material is preferably a chlorinated polyethylene having a chlorine content of 10-50wt.% which is obtained by chlorinating a polyethylene having a molecular weight of 10000-200000 by a solution method or an aqueous suspension method. The printing material is used in any of various forms such as a film or sheet prepared from the chlorinated polyethylene alone or a mixture of the chlorinated polyethylene with a polymer compatible therewith, optionally with addition of additives, a composite laminate of the film or sheet with a composite base material, and a material obtained by coating the film or sheet or the composite base material. The printing material thus obtained is excellent for use as a printing material for gravure, offset printing, letterpress printing, hot stamping, electrostatic printing or the like.
