摘要

In this work, structural and thermal characterization of BF_4 doped copolymer of pyrrole (PPy) with 2-methylbutyl-2-(3-thienyl)acetateprepared by electrochemical polymerization were performed via a pyrolysis mass spectrometry technique. The pyrolysis mass spectrometrydata of the copolymer PPy/PMBTA, and the homopolymers; polypyrrole, PPy, and poly(2-methylbutyl-2-(3-thienyl)acetate), PMBTAwere analyzed and compared. It has been determined that when the electrochemical polymerization of pyrrole was achieved on aPMBTA coated anode through the thiophene moieties of PMBTA, thermal stability of PMBTA chains increased slightly and the decompo-sition of both units followed quite similar pathways indicating an increase in the thermal stability of PMBTA chains unlike what wasobserved for PTSA doped PPy/PMBTA copolymer.
