A process for obtaining a biodegradable polymer comprising steps of esterification and / or transesterification and amidation, step of preliminary polycondensation, step of polycondensation, step of extraction and drying, wherein the use of chain extenders . The present invention presented herein is based on the discovery that the polymers so obtained can achieve improved color as compared to polymers of other methods using a range of viscosity and chain extenders of any desired extent while at the same time being environmentally cleaner And provides a safer, more efficient process. |
