- An aromatic 7t compound such as naphthalene phthalamide, a compound in which a part of the hydrogen bonded to the benzene nucleus of the aromatic amide is replaced with a halogen, and a part of the benzene nucleus of the aromatic amide is replaced with piperazine, 215-dimethylpiperazine ,2,5
Examples include homopolymers and copolymers of compounds substituted with piperazine such as -diethylpiperazine, and lp-benzamide, which is a self-condensation product of aromatic aminocarboxylic acids and derivatives thereof. In the above aromatic polyamide, the amide bond chains are bonded coaxially or in parallel.
Oriented aromatic polyamides are preferred because they have excellent heat resistance and mechanical strength, and poly(P-)unilene phthalamide) is particularly preferred.

成形等の成形方法があげられる。In the present invention, a common solvent solution in which aromatic polyamide and nylon are dissolved is dispersed in the above coagulation solvent to precipitate a polyamide composition in which aromatic polyamide is dispersed in nylon. It is preferable to use the aromatic polyamide in large excess relative to the solution, and the aromatic polyamide becomes fibers with a small diameter, is uniformly dispersed in the nylon, and is a polyamide composition in which the aromatic polyamide fibers and the nylon adhere to each other with good affinity. Preferably, the common solvent solution is fed and dispersed into the vigorously stirred coagulation solvent so as to obtain the following.
1. The obtained polyamide composition is in a state in which aromatic polyamide 1a fibers are now dispersed in nylon, and a molded article such as a fiber, film, or sheet can be obtained from the composition by any conventionally known method. Any molding method may be used, such as press molding, injection molding, roll molding, extrusion molding, and spinning molding.
