Polyphenylene ether-based resin composition and thin wall molded product

Abstract: PROBLEM TO BE SOLVED: To obtain a polyphenylene ether-based resin composition excellent in thermal stability, capable of providing a thin wall molded product excellent in flame retardancy, and useful as a flame retarded insulation sheet or the like by including a polyphenylene ether-based resin, a specific phosphoric acid ester compound and the like, and specifying the content of the phosphorus so as to be a specified value or more. SOLUTION: This polyphenylene ether-based resin composition comprises (A) a polyphenylene ether-based resin such as poly(2,6-diamethyl-1,4-phenylene ether), (B) a phosphoric acid ester compound of formula I (R1 to R3 are each an alkyl, a cycloalkyl or an aryl), (e.g. triphenyl phosphate), and (C) a condensed phosphoric acid ester compound of formula II (R4 to R7 are each H or an organic group with the proviso that the all are not simultaneously H; n is >=1; Z is a 1-10C organic group; q is 0-4), preferably regulated so that the contents of the components A, B and C may be 40-85 wt.%, 1-40 wt.% and 1-40 wt.% respectively, and the content of the phosphorus may be >=1.8 wt.%.

Modified special material for manufacturing flame-retardant turnover box and preparation method of modified special material

Abstract: The invention discloses a modified special material for manufacturing a flame-retardant turnover box and a preparation method of the modified special material. The modified special material is prepared from the following raw materials according to a ratio in parts by weight: HDPP, PVC resin, polyisoprene, pentaerythrityl tetrastearate, polyisobutene, PP-g-ST, polytetrafluoroethylene, glass fibers, ethylene glycol butyl ether, anhydrous calcium chloride, ethylene glycol, dioctyl adipate, activated calcium carbonate, titanium iso-propylate, hydroxypropyl methyl cellulose, a toughening agent, triphenyl phosphate, trimethylolpropane, a coupling agent, epoxy fatty acid butyl ester and chlorinated paraffin. According to the modified special material disclosed by the invention, the modification is performed by adding auxiliary components, and the flame resistance of products is improved to a larger extent on the premises that the properties of other materials are not influenced, and the cost is not increased; the modified special material obtained by the preparation method is good in toughness, and resistant to impact and facilitates processing of the turnover box with good flame retardance and the added values of the products are increased. With the adoption of the method disclosed by the invention, not only are qualified finished products effectively prepared, but also the operation process is very simple, and the mass production is facilitated.

Method of thermographic reproduction by use of powder developer

Abstract: 1,106,199. Thermographic processes. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Dec.21, 1965, No.54185/65. Heading G2C. Thermographic images are produced by imagewise exposing to heat a material comprising a support coated with a compound having supercooling properties so that a liquid latent image is formed and this image is developed by applying a powder developer, the super-coolable material including triphenyl phosphate. Specified materials are triphenyl phosphate alone or admixed with p-tricresyl phosphate, diphenylamine, p-aminodiphenylamine, m-phenylene diamine, acetanilide or o-hydroxy diphenyl. These super-coolable materials may be coated directly on a support or disposed in a polymeric binder before coating. After exposure and development with a developer of the type used in electro-photography, the image may be fixed by heating.

Incorporated fiber and its production

Abstract: PURPOSE:To obtain an incorporated fiber useful for producing ultra-fine fiber and porous fiber, by making a polyester and a polyamide form a clear sea-island structure, comprising one of the polyester inactive to amide-ester exchange reaction and the aliphatic polyamide as an island component and the other as a sea component. CONSTITUTION:An island component having 0.2-0.8mum section area and 2,000-4,000mum volume is formed from one of (A) a polyester inactive to amide- ester exchange reaction and (B) an aliphatic amide and a sea component is composed of the other. The component A is mixed with an inactivating agent (n-octadecyl phosphite, triphenyl phosphite or triphenyl phosphate) to inactivate the residual catalyst in the polyester. A modified polyamide obtained by substituting an amino group at th end of a polyamide with any of groups formula I to formula III (R is H, 1-30C aliphatic, alicyclic or aromatic residue) is preferable as the polyamide of the component B. A block copolymer will not be formed between the component A and the component B in the fiber.

Liquid triaryl phosphates

Abstract: This invention concerns certain new aromatic phosphates useful as plasticizing agents in the preparation of cellulose ether plastic compositions. It is known that certain aromatic phosphates, e. g. triphenyl phosphate, diphenyl mono-o-xenyl phosphate, tri-o-xenyl phosphate, etc., are useful...
