This invention relates to the field of polymers. More specifically, the invention comprises thermoplastic polyurethane elastomers comprising polyesters comprising nitro-substituted dicarboxylic acids that are products obtained by decomposition of polyethylene. The thermoplastic polyurethane elastomers described herein exhibit higher glass transition temperatures and higher Shore A hardness compared to thermoplastic polyurethane elastomers synthesized from similar polyester diols made from virgin monomers that do not contain nitro substitution.

This invention relates to the field of polymers. More specifically, the invention comprises photopolymerizable polyesters and polyester urethane oligomers comprising nitro-substituted dicarboxylic acids that are products obtained by decomposition of polyethylene. The composition described herein are useful for 3D printing, coatings and other uses.

A method of producing an energetic polymer comprises reacting at least one energetic diol with at least one of a diacid halide and a diacid halide derivative to produce a geminal dinitro polyester. A method of producing an energetic binder, and a method of producing an energetic composition are also described.
