More Information
Summary:Method for obtaining biodegradable polymers that comprises a stage of esterification and/or transesterification and amidation reaction, a stage of prepolycondensation, a stage of polycondensation, a stage of extraction and a stage of drying, eliminating in this way the use of chain extenders. The invention herein presented has the main advantage that the polymer thus obtained can achieve all the range of viscosities desired and with an improved colour compared to the polymer from other methods, where chain extenders are used, while providing a more efficient process, environmentally cleaner and safer for the operatives.
