Patent number: 4692490Abstract: The flame resistance of blends of polyphenylene ether resin and high impact polystyrene is upgraded by the inclusion of a combination of a polybrominated 1,4-diphenoxybenzene and antimony oxide. The resulting composition exhibits good thermal stability and is more resistant to undergoing juicing and blooming in comparison with the use of polybrominated diphenyl oxides.Type: GrantFiled: March 19, 1986Date of Patent: September 8, 1987Assignee: General Electric CompanyInventor: Visvaldis Abolins

Patent number: 4681902Abstract: This invention relates to flame retardant phenol aldehyde foams which have a k value below 0.020 W/mk. The foams have as flame retardants a blend of a halosubstituted diphenyl oxide and an organic phosphorus compound. The feature of the invention is that unlike conventional flame retardants, the blend now used does not adversely affect the low k value i.e. the low thermal conductivity of the foam.Type: GrantFiled: November 3, 1986Date of Patent: July 21, 1987Assignee: BP Chemicals LimitedInventors: Alexander W. S. Duncan, David G. Summers, Kenneth C. Thomas
