20090149561 | EXTRUDED POLYMER FOAMS CONTAINING BROMINATED 2-OXO-1,3,2-DIOXAPHOSPHORINANE COMPOUNDS AS FLAME RETARDANT ADDITIVES - Extruded polymer foams are prepared using 5,5-bis(bromomethyl)-2-oxo-1,3,2-dioxaphosphorinane or brominated 2-oxo-1,3,2-dioxaphosphorinane compounds. The brominated FR additives unexpectedly are stable at the extrusion temperatures, and provide excellent flame retardancy to the foams. | 06-11-2009 |
20090292079 | Process for brominating butadiene/vinyl aromatic copolymers - Butadiene copolymers are brominated in solution using bromine as the brominating agent. The bromination is conducted in the presence of an excess of an aliphatic alcohol, relative to the amount of bromine that is used. The bromination proceeds rapidly at mild conditions, and is selective in that only aliphatic carbon-carbon double bonds are brominated, and unwanted bromination at tertiary carbon atoms is largely or completely avoided. The resulting brominated polymers are characterized in having very good thermal stability. | 11-26-2009 |
20110034573 | PHOSPHORUS-SULFUR FR ADDITIVES AND POLYMER SYSTEMS CONTAINING SAME - Phosphorus-sulfur compounds have flame retardant activity in organic polymer systems. The phosphorus-sulfur compounds can be represented by the structure: | 02-10-2011 |
20110135948 | Composition for making metal matrix composites - In one embodiment, a composition ( | 06-09-2011 |
20130249135 | POLYSTYRENE MELT EXTRUSION PROCESS - Extruded polystyrene foams are made with an added brominated styrene-butadiene polymer as a flame retardant. The blowing agent is a mixture of carbon dioxide, ethanol and water, which may also contain a C | 09-26-2013 |
20140116248 | Selective Gas Transport Films that Contain Brominated Styrene-Butadiene Copolymers - Brominated styrene-butadiene copolymers are useful gas transport films. The gas transport films are made by brominating a starting styrene-butadiene copolymer, and then forming the brominated styrene-butadiene copolymer into a film The film may contain a blend of the brominated styrene-butadiene copolymer with one or more other polymers. The films have excellent selectivities between certain pairs of gasses, and exhibit high gas transport rates for various gasses such as carbon dioxide and water vapor. | 05-01-2014 |
20140187692 | Impact-Modified Styrenic Polymers Containing Brominated Vinyl Aromatic-Butadiene Copolymer - Impact-modified polystyrene resins such as HIPS and ABS resins are blended with a brominated vinyl aromatic-butadiene copolymer. The brominated copolymer is an effective flame retardant in these compositions, allowing in many cases a V-1 rating to be achieved in the UL-94 vertical burn test. | 07-03-2014 |
20140343180 | THERMOSET POLYURETHANE FOAM CONTAINING BROMINATED POLYMERIC FLAME RETARDANT - Prepare a thermoset polyurethane foam containing a brominated polymer with aliphatic bromine as a flame retardant. | 11-20-2014 |
