In order to improve the properties of their individual components, the compositions of dibutyrylchitin (DBC) and aliphatic polyesters (PCLG) were prepared and examined. The studied systems are homogeneous in a wide range of composition and molar masses of their components. The homogeneities of the blends made it possible to form smooth and transparent films, which were investigated by mechanical testing. It was found that the chemical structure and molar mass of a polyester component had an effect on mechanical properties of the systems. The films were subjected to hydrolytic degradation in media of various pH values (4.0, 7.4 and 13.0) at 37 °C. Furthermore, it was found that the molar mass and composition of the PCLG component clearly affected the rate of hydrolysis of the studied systems. The effect of hydrophilicity of the DBC/PCLG blends on degradation rate was also investigated. Consequently, by an appropriate choice of the components it is possible to control the profile of hydrolytic degradation of the DBC/PCLG systems.
