Abstract:Copolymers of starch grafted with poly(lactic-co-glycolic acid) and poly(lactic-co-glycolic acid-co-caprolactam) were prepared by direct polycondensation of soluble starch with lactic acid, glycolic acid and caprolactam in the presence of stannous chloride SnCl2]. The chemical microstructure of the resultant grafted copolymers was clarified by NMR spectroscopy and the thermal properties was investigated by differential scanning calorimetry (DSC) and thermogravimetric (TG) analysis.
Keywords:Biodegradable  Starch  graft  Direct polycondensation
