Abstract

The development of biodegradable blends is an important option for reducing environmental impacts generated by the use of plastics, besides increasing the knowledge biodegradable polymers and its associations. In this contribution, rheological and thermal characteristics of neat PCL and PBAT and PCL/PBAT blends melt mixed in an internal laboratory mixer were evaluated. The results suggested that the blends are immiscible but there is a strong interaction between the components. Crystallization kinetics can be represented by Pseudo-Avrami model.
