| abstract | ABSTRACT OF THE DISCLOSURE This invention to fire-resistant polyphosphazene polymers which exhibit a high degree of flame retardancy and which do not generate large amounts of smoke or toxic products when ignited or exposed to relatively high temperatures. More specifically, it relates to low density polyphospha-zones as foams and coating materials with outstanding thermal stability and to vulcanizable compositions of poly(phosphazenes) and insulating foams made therefrom. Additionally, the invention provides a process for the preparation of fire retardant, low smoking, thermally stable oil resistant vulcanizates and closed cell foams which are made from the poly(phosphazenes) polymers described above. The process comprises preparing a suitable mixture; milling the mixture; cutting the product to a preform charge; and either molding preform charge under heat and pressure to produce a vulcanizate or molding said preform charge to produce a precured slab which is expanded and vulcanized in an oven to produce a foam. In the case of vulcanizates, the mixture be milled consists of poly(phosphazene) polymer, filler, MgO or ZnO, reinforcing filler, plasticizer or processing aid, a compound having alkenyl functionality and a curing agent. For foams, the mixture to be milled consists of particularpoly(phoshazene) polymer, hydrated alumina, MgO or Zno, plasticizer or processing aid, a compound having alkenyl functionality, a blowing agent and a curing agent. |
