FIELD: chemistry.
SUBSTANCE: invention relates to industrial methods of producing biodegradable copolymer of polyester and etheramide. Disclosed is a method of producing a biodegradable copolymer of polyester and etheramide, involving a step of esterification and/or re-esterification and amidation, stage of preliminary polycondensation, stage of polycondensation, optional extraction stage, stage of drying and final stage of extrusion with additives.
EFFECT: technical result is the disclosed method enables to release a copolymer with a wide range of viscosity, as well as with different content of additives and improve the colour of the product, while being more environmentally friendly and safer for all maintenance personnel compared to available analogues.
