Popis:	This study presents synthesis of novel block copolymers of thienyl end capped ethoxylated nonyl phenol and polypyrrole with silver nanoparticles via chemical oxidative polymerization by iron (III) chloride. Ethoxylated nonyl phenol (ENP) was reacted with 2-thiophenecarbonyl chloride (ThCCl) in order to synthesize a macromonomer containing thienyl end-group (ENP-ThC). Then copolymers of ENP-ThC and pyrrole were synthesized by chemical oxidative polymerization using iron (III) chloride as an oxidant. During this reaction, silver nitrate (AgNO 3 ) solution was added in order to increase its conductivity and to give the copolymer anti-microbial property. The synthesized block copolymers (ENP-ThC-b-PPy) with silver nanoparticles were characterized by spectroscopic analysis and the electrical conductivities were investigated with 4-point probe technique. The obtained samples were also characterized morphologically by Scanning Electron Microscope (SEM).
