Synthesis and properties of linear polyphosphazenes with different side groups

摘要

@@In this paper, four linear polyphosphazenes with different side groups were synthesized by the reaction of poly(dichlorophosphazene) with their corresponding sodium salts. The poly (dichlorophosphazene) was obtained by the ringopening reaction of Hexachlorocyclotriphosphazene. The structures and properties of these polymers were characterized and the influence of their thermal performance was studied. The design of linear polyphosphazene structure is the flame-retardant application in rubber, plastic and polyester fiber, because the superiority of the structure is the good compatibility, high efficient flame resistance and non-migration et al for base polymer.
