Original Paper


A diblock copolymer consists of ε-caprolactone, and tetrahydrofuran was synthesized by using a novel natural amino acids such as penicillamine and tyrosine as a chemical initiator in the presence of stannous octoate as a catalyst through bulk polymerization method under nitrogen atmosphere with mild stirring condition. The synthesized diblock copolymer was treated with AgNO3 to form a nano-Ag-tagged diblock copolymer. The above-synthesized polymer systems were characterized by various analytical tools such as FTIR spectroscopy, NMR spectroscopy, fluorescence emission spectroscopy, circular dichroism, gel permeation chromatography, FESEM, HRTEM, EDX, DSC and TGA. Its applications toward catalytic reduction of p-nitrophenol (NiP), wound healing activity and low-temperature splinting activity were tested. Due to the incorporation of poly(tetrahydrofuran) (PTHF), the % elongation value of the diblock copolymer was increased but the DSC and TGA results showed depressed results. The HRTEM declared the size of Ag nanoparticle as < 50 nm. From the values of UV–visible absorbance, apparent rate constant (kapp) was determined and compared with the literature report.
