Production of flame retardant

Abstract: PURPOSE: To obtain a novel flame-retardant containing phosphorus and halogen in the molecule, by reacting a phosphoric acid ester with a halogenated aromatic compound having two alcoholic hydroxyl groups. CONSTITUTION: A flame-retardant resistant to bleeding can be produced by (1) compounding (A) a phosphoric acid ester preferably having aromatic ring (e.g. triphenyl phosphate) with (B) a halogenated aromatic compound having two alcoholic hydroxyl groups in the molecule [e.g. 2,2-bis(3,5-dibromo-4-β-hydroxyethoxyphenyl)-propane] at a molar ratio (A/B) of 1/(0.1W2) and (2) heating the mixture at about 80W250°C, preferably 130W170°C in the presence of a basic catalyst (e.g. K 2 CO 3 , triethylamine, etc.) (0.01W2wt% based on the sum of the components A and B) and in the absence of solvent, thereby effecting the ester- exchange and the polymerization of the components.

Adhesive of polyester to rubber

Abstract: PURPOSE:The titled adhesive, consisting of a specific phosphate compound, an epoxy resin, etc, a synthetic copolymer latex and resorcin-formaldehyde precondensate, and having improved tensile strength and adhesive force when subjected to high temperatures for a long time in a rubber compound CONSTITUTION:An adhesive obtained by incorporating (A) a phosphate compound of the formula [R1-R3 are (alkyl)phenyl, alkoxyalkyl, halogenated alkyl or alkene], eg triphenyl phosphate, with (B) one or more selected from blocked isocyanates, epoxy resins and p-chlorophenol resins, (C) a synthetic copolymer latex, eg styrene-butadiene copolymer latex, and (D) a resorcin-formaldehyde precondensate, preferably at (1:05)-(1:3) mixing molar ratio between the resorcin and the formalin Preferably, the amount of the component (A) is 001- 20ptswt based on 100ptswt component (C), and the weight ratio of the components (A) to (C) is (2:1)-(10:1) based on the solid content

Highly impact-resistant polyphenylene ether resin composition

Abstract: PURPOSE: To improve flame retardance, resistance to impact and heat, etc., by blending a polystyrene resin, a specified copolymer elastomer, a graft copolymer and an arom. phosphate ester with a polyphenylene ether. CONSTITUTION: 60W90pts.wt. polyphenylene (A), 10W30pts.wt. polystyrene resin (B), 2W15pts.wt. acrylonitrile/conjugated diene compd. copolymer elastomer (C), 2W10pts.wt. graft copolymer (D) obtd. by graft reacting a butyl rubber with an unsaturated polyolefin in the presence of a bifunctional phenol medium, and 5W 20pts.wt. arom. phosphate (E) such as triphenyl phosphate are mixed together to obtain the titled resin compsn., each quantity being per 100pts.wt. of the combined quantity of components A, B, C, D.

Production of cellulose ester film for photographic material

Abstract: PURPOSE:To obtain the titled film which has excellent mechanical strength with good workability, by immersing a cellulose ester in a non-swellable solvent to lower its viscosity, dissolving the ester is an org. solvent and molding it into a film. CONSTITUTION:A cellulose ester such as cellulose triacetate or cellulose acetate butyrate is immersed in a non-swellable solvent such as benzene or toluene. The mixture is stirred for 24hr or longer. A plasticizer such as triphenyl phosphate or dimethoxy-ethyl phthalate is blended with said cellulose ester whose viscosity has been lowered by the above immersion treatment. The mixture is dissolved in an org. solvent such as methylene chloride or methanol. The resulting soln. is extruded into a film on a substrate and the solvent is evaporated. The solid film is peeled from the surface of the substrate to obtain the desired cellulose ester film for photographic materials.
