Document Type and Number:
WIPO Patent Application WO/2010/120020
Kind Code:
A1
Abstract:
The present invention relates to a molecular miscible aromatic polyamide blend solution having optical anisotropy, which is obtained by homogeneously blending a high crystallinity para-aromatic polyamide polymer with a non-crystalline polymer in their molecular states, a preparation method thereof, an aromatic polyamide blend fiber obtained therefrom and a method for dyeing the fiber. The molecular miscible blend solution of an aromatic polyamide and a non-crystalline polymer according to the present invention is prepared by dissolving an aromatic polyamide polymer having a recurrent unit expressed in the following formula (I) and polyvinyl pyrrolidone at an amount of 5 to 100% by weight of the aromatic polyamide, in a polar organic solvent containing an inorganic salt: [ - NH - R - NH - CO - R'- CO - ]n....
