The copolymers were characterized by various analytical techniques like FTIR, NMR, UV-visible, Fluorescence, XPS, SEM, FESEM, TEM, DSC, TGA and GPC. Finally, the water contact angles of the copolymers were tested. The results indicated that the thermal, fluorescence, molecular weight and water contact angle properties of the copolymer depended on the structure and nature of the copolymers. The analytical results also declared that the interface between hydrophobic and hydrophilic region had the nano structure, due to the reduction in the size. On heating under air atmosphere the hydrophilic segments degraded first followed by the hydrophobic segments.en-US
