Abstract
Abstract Poly(silyloxytetraalkylbiphenyleneoxide)s are provided resulting from the reaction between a tetraalkylbiphenol, such as tetramethylbiphenol and an organosilicon material such as dimethyldichlorosilane or octamethylcyclotetrasilazane. The poly(silyloxytetraalkylbiphenyleneoxide)s are flame retardant film-forming materials useful as high performance injection moldable thermoplastic and dielectrics.
