Synthesis of new thermo/pH sensitive drug delivery systems based on tragacanth gum polysaccharide.In this study, new pH/temperature responsive graft copolymers were synthesized based on natural Tragacanth Gum (TG) carbohydrate and their controlled drug release was investigated.  Different techniques such as FT-IR, (1)H NMR, gel permeation chromatography (GPC), thermo-gravimetrical analysis (TGA) and scanning electron microscopy (SEM) were used to verify the successful synthesis of graft copolymers (TG-g-PDMAEMA-PCL-mPEG)s.
