20080269416 | Flame retardant halogenated polymer compositions - A halogenated aryl ether oligomer is formed by halogenation of an aryl ether oligomer and is useful as a flame retardant for flammable macromolecular materials. Typically, the halogenated aryl ether oligomer comprises the following repeating monomeric units: | 10-30-2008 |
20090156714 | Flame retardant compositions - A flame retardant composition comprises (a) an organic halide flame retardant in the form of a powder having an average particle size less than or equal 15 microns and (b) an inorganic oxide in an amount up to 5% of the total weight of the organic halide and the inorganic oxide. | 06-18-2009 |
20090221754 | POLYMER COMPOSITIONS OF BROMOSTYRENES HAVING CONTROLLED MOLECULAR WEIGHT - A controlled molecular weight polymer of styrene is provided having bromine substituted thereon. Control of molecular weight is achieved by the use of alphα-methyl styrene dimer as a chain transfer agent. The brominated polymer of styrene is useful as a flame retardant, particularly for polyamides giving improved properties including color retention after molding. | 09-03-2009 |
20100120990 | PROCESS FOR CONTROLLING THE MOLECULAR WEIGHT OF POLYMERS OF BROMOSTYRENE - A controlled molecular weight polymer of styrene is provided having bromine substituted thereon. Control of molecular weight is achieved by the use of alpha-methyl styrene dimer as a chain transfer agent. The brominated polymer of styrene is useful as a flame retardant, particularly for polyamides giving improved properties including color retention after molding. | 05-13-2010 |
20100160516 | FLAME RETARDANT HALOGENATED PHENYL ETHER BLENDS - A flame retardant blend comprises at least first and second halogenated non-polymeric phenyl ethers having the general formula (I): | 06-24-2010 |
20110040003 | FLAME RETARDANT HALOGENATED POLYMER COMPOSITIONS - A halogenated aryl ether oligomer is formed by halogenation of an aryl ether oligomer and is useful as a flame retardant for flammable macromolecular materials. Typically, the halogenated aryl ether oligomer comprises the following repeating monomeric units: | 02-17-2011 |
20110054086 | FLAME RETARDANT POLYMERS AND ADDITIVE SYSTEM FOR IMPROVED VISCOSITY POLYMERS - A flame retardant thermoplastic polymer composition, having a major amount of a thermoplastic polymer and a flame retardant additive comprising a phosphinic acid salt, a zinc salt and a melamine salt, in an amount effective to provide flame retardance to said polymer, and a low Tg glass containing phosphorous, tin and fluorine, in an amount sufficient to reduce the shear viscosity of the composition to less than about 10 Pa·s at a shear rate of about 10,000/sec and a temperature of 280° C., as measured by ASTM D-3835 is provided. Also provided is a flame retardant composition comprising phosphinic acid salt, a zinc salt, a melamine salt and the low Tg glass and a process for forming the flame retardant thermoplastic polymer composition by incorporating the flame retardant composition into the molten polymer. | 03-03-2011 |
20120065297 | FLAME RETARDANT HALOGENATED PHENYL ETHERS - A halogenated non-polymeric phenyl ether flame retardant is described having the general formula (I): | 03-15-2012 |
