    • Polyphosphazene blends and foams thereof are described. The blends comprise of at least one polyphosphazene copolymer having a Young's Modulus of up to about 5.times.10.sup.8 dynes/cm.sup.2 and at least one polyphosphazene homopolymer or copolymer having a Young's Modulus of at least about 5.times.10.sup.8 dynes/cm.sup.2. The copolymers used to prepare the blends comprise randomly repeating units represented by the formulas ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and are hydrogen, a C.sub.1 - C.sub.10 linear or branched alkyl radical, or a C.sub.1 - C.sub.4 linear or branched alkoxy radical substituted on any sterically permissible position on the phenoxy group, with the proviso that when R.sub.2 is alkoxy, R.sub.1 and R.sub.2 are different. The blends of this invention can be formed into sheets or films, or into flexible or semi-rigid foams. The blends are extremely fire retardant and produce low smoke loads, or essentially no smoke, when heated in an open flame.

    • Poly(aryloxyphosphazene) polymers and foams thereof having di(C.sub.1 -C.sub.10)alkylaminophenoxy groups are described. The polymers consist of the units which occur in a nonregular fashion and are represented by the following general formula: ##STR1## wherein R.sub.1 and R.sub.2 are the same or different and are C.sub.1 -C.sub.10 linear or branched alkyl radical. Copolymeric dialkylaminoaryloxy-aryloxyphosphazenes are disclosed represented by units of the general formula: ##STR2## wherein R.sub.1 and R.sub.2 are defined above and R represents hydrogen, halogen, C.sub.1 -C.sub.10 linear or branched alkyl radical, or C.sub.1 -C.sub.4 linear or branched alkoxy radical substituted on any sterically permissible position on the other phenoxy group. The radical NR.sub.1 R.sub.2 is substituted in the meta or para position on the phenoxy radical. The polymers are elastomers, have desirable tensile strengths and may be used to form flexible or semi-rigid films, sheets, and foams. The polymers are extremely fire retardant and produce low smoke loads when heated in an open flame. They readily form salts with mineral acids that are water soluble.

    • Poly(aryloxyphosphazene) copolymers and foams thereof having a significant portion of C.sub.1 - C.sub.4 alkoxyphenoxy groups are described. The copolymers consist of the units which occur in a nonregular fashion and are represented by the following general formulas: ##STR1## wherein R.sub.1 represents a C.sub.1 - C.sub.4 linear or branched alkyl radical in the ortho-, meta-, or para-position, and R.sub.2 represents hydrogen, a C.sub.1 - C.sub.10 linear or branched alkyl radical, or a C.sub.1 - C.sub.4 linear or branched alkoxy radical substituted on any sterically permissible position on the phenoxy group, with the proviso that when R.sub.2 is alkoxy, OR.sub.1 and R.sub.2 are different.
