Copolymerization of Pyrrole and Thienyl end Capped Poly(dimethylsiloxane) by Iron (III) Chloride

This study presents synthesis of novel block copolymers of thienyl end capped polydimethylsiloxane and polypyrrole via chemical oxidative polymerization by iron (III) chloride. Mono hydroxy terminated poly (dimethylsiloxane) (MH.PDMS) was reacted with 2-thiophenecarbonyl chloride (ThCCl) in order to...

Description
Summary:This study presents synthesis of novel block copolymers of thienyl end capped polydimethylsiloxane and polypyrrole via chemical oxidative polymerization by iron (III) chloride. Mono hydroxy terminated poly (dimethylsiloxane) (MH.PDMS) was reacted with 2-thiophenecarbonyl chloride (ThCCl) in order to synthesize a polymer containing thienyl end-group (PDMS-ThC). Then copolymers of PDMS-ThC and pyrrole were synthesized by chemical oxidative polymerization using iron (III) chloride as an oxidant. The synthesized block copolymers (PDMS-ThC -b-PPy) 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).
