Synthesis of azidourethane block copolymers

详细

Methods of structuring thermoreversible urethane block copolymers on the basis 3,3-bis-(azidomethyl)oxetane (BAMO) and 3-(azidomethyl)-3-methyloxetane (AMMO) were developed for the first time. Type (AB)_n copolymers of BAMO and AMMO have an amorphous crystalline structure but differ from the type B(AB)_n copolymers in that they contain less crystal phase and have a higher glass transition temperature and better physicomechanical properties.
