Synthesis of Energetic Multi-Phase Polymers

Abstract

A series of ABA block copolymers with C30-alkane or poly(BAMO) hard blocks, and azido/nitrato polyether or nitro/fluoro polyformal soft blocks was synthesized. The polymers with polyether soft blocks have poor mechanical properties but low melt viscosities, whereas the polymers with polyformal soft blocks have better mechanical properties but high melt viscosities. Several additional ABA block copolymers were prepared with a combination of azido/nitrate polyether and fluoro polyformal soft blocks. Preliminary characterization shows these polymers to have more acceptable properties overall. Plasticization of the ABA polymers with polyformal soft blocks lowers their TG and melt viscosity.
