The invention relates to a polymer for tissue engineering from biodegradable polyphosphazenes, having photopolymerizable side groups, wherein the side groups of the polyphosphazenes are formed exclusively from amino acids and/or amino acid derivatives, which are bonded to the backbone of the polyphosphazene via the amino group of the amino acid and to a spacer attached to the acid group with a carbon chain of length m, which has a vinyl group at the free end, wherein m=0 to m=10.

The instant disclosure relates to phosphorus-containing compounds that can be used to form flame retardant phosphorus-containing resins, and also can serve as a hardener for a flame retardant epoxy resin compositions. In particular, the phosphorus-containing compounds are modified with acyloxy groups (O(CO)R), as shown below. Incorporation of the acyloxy groups results in resins that are water resistant and exhibit improved dielectric properties. ##STR00001##

Polymers useful for imparting flame resistance to fibers and textiles are provided herein. The polymers are water-soluble, phosphine oxide-containing polymers that may be reaction products of hydroxymethyl phosphonium salts or hydroxymethyl phosphines with linking monomers, wherein at least 20% of the phosphorous atoms of the polymer are present as phosphine oxides. Formulations including the polymers and methods of using the polymers to impart flame resistance to fibers and textiles are also disclosed.

Phosphazenium-based ionomers and methods of making them are disclosed. The ionomers are useful in making membranes for fuel cells and other devices that benefit from extremely base-stable membranes. The polymers (ionomers) contain repeating units of formula: ##STR00001##
in which all of R.sup.1, R.sup.2, W, Y and Z are hydrocarbon.
