Summary
Thermal transitions of poly (N-alkyl-3,6-carbazolylene)s were analyzed by differential scanning calorimetry. Glass transition temperatures (Tg) of the polymers were found to decrease by increasing side-chain length. As-prepared polymers bearing n-octyl pending groups exhibit crystallinity but no crystallisation from the melt was observed. Recrystallisation of the samples thermally treated was obtained by solvent treatment. Crystallinity was associated to an ordered phase involving the main-chain units.
