Polyflactic acid material

As a raw material for the production of monomers used in the synthesis of polymers, to replace oil-derived chemicals, such as polyethylene which can be derived from ethanol obtained by fermentation of starch or of lactic acid, used in the production of polyflactic acid) (PLA) [38]. 

Starch is the major carbohydrate reserve in higher plants and has been one of the materials of choice since the early days of human technology. Recently, starch gained new importance as a raw material in the production of bioplastics, in particular for use in the synthesis of monomers to produce polymers such as polyflactic acid), and after chemical modification and thermomechanical processing, to produce the so-called thermoplastic starch. 

Polymers in the group of polyesters, specifically the family of polyflactic acid) (PLA), polyfglycolic acid) (PGA), and copolymers of lactic and glycolic acids (PLGAs), as well as poly(P-hydroxybutyric acid) (PHB) most closely fulfilled the criteria outlined above, including biocompatibility, processability, and controlled degradation [8]. These polymers, many descendant of absorbable suture materials developed a couple of decades ago, were approved for in vivo use by the Food...
