用吡咯钾盐封端活性双官能偶氮聚四氢呋喃（azo-PTHF），得到具有电化学活性端基的聚合物。该聚合物进一步用于合成聚四氢呋喃-聚苯乙烯（PTHF-b-PS-b-PTHF）嵌段共聚物。这些聚合物使用恒电位电解用聚吡咯电化学封闭（PPy/Azo-PTHF和PPy/PTHF-b-PS-b-PTHF）。在电解过程中使用两种不同的溶剂-电解质对。用循环伏安法（CV）、傅里叶变换红外光谱（FTIR）、差示扫描量热法（DSC）、热重分析（TGA）、扫描电镜（SEM）、核磁共振谱（NMR）和凝胶渗透色谱（GPC）对原始共聚物和嵌段共聚物进行了表征。使用四探针技术测量电导率。
Living bifunctional azo-polytetrahydrofuran (azo-PTHF) was terminated with pyrrolyl potassium salt to yield a polymer with electrochemically active functional end groups. This polymer is further used to synthesize polytetrahydrofuran-polystyrene (PTHF-b-PS-b-PTHF) block copolymer. These polymers are electrochemically blocked with polypyrrole using constant potential electrolysis (PPy/Azo-PTHF and PPy/PTHF-b-PS-b-PTHF). Two different solvent-electrolyte pairs were used during electrolysis. Characterizations of pristine and the blocked copolpolymers are based on Cyclic Voltammetry (CV), Fourier Transform Infrared Spectroscopy (FTIR), Differential Scanning Calorimetry (DSC), Thermal Gravimetry Analysis (TGA), Scanning Electron Microscope (SEM) Nuclear Magnetic Resonance Spectroscopy (NMR) and Gel Permeation Chromatography (GPC). Conductivities were measured using a four-probe technique.
