The use of thermoplastic starch in compositions based on polylactic acid is of interest from the point of view of controlling the physicomechanical properties of materials and the time of biodegradation. The effect of thermoplastic starch containing sorbitol and / or glycerin as plasticizers on the resistance of compositions based on polylactic acid to thermal and thermomechanical action was studied. The physicomechanical properties of the compositions and their resistance to biodegradation under composting conditions have also been determined.

Polylactic acid, due to such properties as biocompatibility, inertness to aggressive media of the human body and biodegradability is becoming more widespread in medicine, particularly in traumatology and reconstructive surgery. The article discusses modern developments in the field of biodegradable medical products based on polylactic acid that are already on the market or planned for production in the near future. Also considered the major major producers of polylactic acid.
