摘要:
The object of this invention is to provide a dope that has excellent formability and can be formed into a fiber, a film, pulp-shaped particles and the like by a wet method. The object of this invention is also to provide a process for the production of a fiber excellent in heat resistance, strength and elastic modulus.This invention provides a dope and a process for the production of a fiber from the dope, the dope comprising a polyamide and a basic solvent, the polyamide containing a recurring unit of the following formula (I), wherein Ar1 represents at least one substituent selected from the group consisting of and having an inherent viscosity of 1.0 or more, the dope has a polyamide concentration of over 10% by weight but not more than 25% by weight and exhibits optical anisotropy at 50° C.
