Deformation and Strength Characteristics of Fatty Aromatic Block Copolymers Based on Polycarbonate

Polycarbonate—poly(tetramethylene oxide) block copolymers were synthesized using acceptor—catalytic polycondensation. The phase composition and deformation and strength characteristics of the block copolymers were studied using various methods. It was shown that rigid and elastic blocks were partially aligned in block copolymers containing up to 30 mass% of poly(tetramethylene oxide) blocks. Phase separation of microscopic blocks occurred at higher contents. The deformation and strength properties of the block copolymers were studied. Properties of thermoplastics or thermoplastic elastomers appeared depending on the polymer composition.
