Abstract: | Polyurethane (PU)–polyacrylic acid (PAAc) multiblock copolymers have been prepared via a macroiniferter technique, and were tested for living mechanism, thermal, and water swell of the cast films. It was found that molecular weight of the PU–PAAc block copolymers linearly increased while molecular weight distribution decreased with conversion. As the PAAc content increases, water swell of the cast films and crystalline melting temperature (Tm) of PU decreased while glass transition temperature of PU increased. |
