Abstract It has been proved that introducing isocyanurate into polymer chains
could improve the flame retardancy of polymers. We describe in this work the
synthesis and the thermal property study of three thermoplastic polyisocyanurates,
which are polyisocyanuratoamide (PICA-6), polyisocyanurato(ester amide)
(PICEA-6) and polyisocyanurato(urea ester) (PICUE-6). These polymers show
similar and improved thermal stability with the existence of isocyanurate rings.
PICA-6 is more crystalizable than the rest two and the melting temperature is
found to be around 240°C but it still crystalizes slowly. For PICEA-6 and
PICUE-6, only glass transition can be observed on the DSC traces. The glass transition temperature follows… More >
