Synthesis and characterization of novel PCA-PEG-PCA triblock copolymer
Using chloroacetic acid(CA) and polyethylene glycol(PEG) as raw material,polyacetic acid-polyethylene glycol-polyacetic acid(PCA-PEG-PCA) triblock copolymer was synthesized by solution polycondensation.The triblock copolymer was characterized by FT-IR spectroscopy,X-Ray Diffraction and DSC.The structure of copolymer was confirmed by FT-IR.The crystallinity of compolymer was 51.24% investigated by XRD,and the result of DSC showed the PCA and PEG was homogeneous with a good compatibility.
