The Effect Of Potassium Hydroxide On The Polymerization Of Trichlorophenol, Pyrrole And Thiophene By Microwave InitiationUnsal Gungor, Elif Mufide 01 June 2008 (has links) (PDF)
The synthesis of black conducting polymer (CP) and/or crosslinked polymers
(CLP) and/or radical ion polymer (RIP) and/or white polymers (WP) and/or
orange polymer (OP) were achieved by using KOH with TCP, pyrrole and
thiophene via microwave energy in a very short time interval.
Polymerizations were carried out by constant microwave energy with different
time intervals varying from 1 to 25 min / or at constant time intervals with
variation of microwave energy from 90 to 900 watt / or varying the water content
from 0, 0.5 to 5 ml at constant time intervals and microwave energy, or at
constant time interval, water content, microwave energy with variation of
amount of KOH 0.03 mol to 6x10-4 mol. The effects of heating time, microwave
energy, water content and amount of KOH on the percent conversion and the
polymer synthesis were also investigated.White, orange polymers and radical ion polymers were characterized by FTIR
(Fourier Transform Infrared), 1H-NMR (Proton Nuclear Magnetic Resonance),
13C-NMR (Carbon-13 Nuclear Magnetic Resonance), TGA/ FTIR (Thermal
Gravimetric Analysis / Fourier Transform Infrared), DSC (Differential Scanning
Calorimeter), SEM (Scanning Electron Microscope), ESR (Electron Spin
Resonance), GPC (Gel Permeation Chromatography), UV-Vis (UV-Visible
Spectroscopy) and Light Scattering. Conducting and crosslinked polymers were
characterized by FTIR, TGA/ FTIR, DSC, SEM, ESR, XRD (Powder Diffraction
X-Ray) and conductivity.
