Abstract :
The conversion process of PPV precursor containing a tetrahydrothiophene group was studied by different techniques. Conversion temperatures were chosen according to DSC measurements. Conversion included elimination of water and tetrahydrothiophenium groups which leads to the increase of Tg, followed by modulated DSC technique, for the precursor because of elimination of plasticizing components. X-ray diffraction showed densification of the material going along with an increase in conjugation length.
