Abstract

Properties of the biodegradable polymers like PDLLA and PCL can be modified by blending them with each other and with other polymers like Starch. In the present study we have prepared blends of PDLLA, PCL and starch in different proportions and then subjected to microwave radiation. Using microwave, time of reaction has been reduced to 3–30 min as microwave radiation is associated with more even distribution of heat. The results indicate a direct linkage between the polymers indicating the formation of a chemical linkage between the two molecules as opposed to just a physical blend.
