摘要:
The novel compound 5,6,7,8-tetrabromo-1,2,3,4-tetrahydro-naphthalene (tetrabromotetralin) of the formula: ##STR1## was prepared using 1,2,3,4-tetrahydro-naphthalene as the starting compound. Tetrabromotetralin was employed to prepare flame-retardant plastic compositions.
摘要:
A process is described, in which poly(pentabromobenzylester acrylate) is prepared by the thermal bulk polymerization of pentabromobenzylester monoacrylate.A product with excellent properties is obtained with short reaction times and without any additive.
摘要:
Novel derivatives of 3,3'-oxy-bis{[2,2'-di(bromomethyl)]propanoic acid}of formula (1) ##STR1## in which Y represents OR, chlorine or NH--R and wherein R represents hydrogen or an alkyl, aralkyl or aryl group, in which the alkyl, aryl and aralkyl groups are unsubstituted or substituted with 1 to 5 bromine atoms, are described.The novel derivatives of the invention have improved thermal properties and a high content of bromine, and are particularly suitable as flame-retardant agents. Methods of preparation of these novel compounds are described.
摘要:
A flame retardant composition for flammable plastic materials and a method for producing the same are disclosed. The flame retardant composition comprises 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine that contains 1 to 1000 ppm of a metal species of a water-insoluble polyvalent metal compound selected from the group consisting of oxide, hydroxide, carbonate, phosphate, sulfate and silicate present in the particles of 2,4,6-tris(2,4,6-tribromophenoxy)-1,3,5-triazine. The flame retardant composition is produced by reacting an alkali metal salt of 2,4,6-tribromophenol and cyanuric chloride in the presence of said water-insoluble polyvalent metal compound.

Isolated polynucleotide sequences exhibiting endothelial cell specific promoter activity, novel cis regulatory elements and methods of use thereof enabling treatment of diseases characterized by aberrant neovascularization or cell growth are disclosed.
摘要:
The present invention provides a process for manufacturing acrylate esters of trinol, dinol, and didinol, which avoids the undesired thermopolymerization of the esters and provides highly pure monomers for the preparation of plastic lenses.
摘要:
The present invention discloses novel halogenated flame retardant formulations that effectively flame retard textiles at low binder and/or the flame retardant synergist contents, novel modes of application thereof on textiles, and flame-retarded textile fibers and fabrics which are treated by these formulations.
