Abstract

Herein we report on the synthesis of reactive poly (p-phenylene terephthalamide)(PPTA) oligomers and the preparation and characterisation of aramid fibres thereof. Methacrylate and maleimide reactive end-groups were found to be sufficiently stable in H2SO4 at 85° C and they were used to prepare reactive PPTA oligomers. Lyotropic spin-dopes could be prepared with up to 20 wt% of reactive oligomer (Mn= 3900 g mol− 1) and this ...
