| 摘要 |
The invention concerns fiber, and a process for making same, the fiber comprising a mixture of at least a first polymer and a second polymer, the first polymer having a structure derived from the reaction of one or more amine monomers and a plurality of acid monomers, wherein the one or more amine monomers includes at least 60 mole percent 5(6)-amino-2-(p-aminophenyl)benzimidazole, and the plurality of acid monomers include those having a structure of Cl—CO—Ar1-CO—Cl & Cl—CO—Ar2-CO—Cl wherein Ar1 is an aromatic group having para-oriented linkages and Ar2 is an aromatic group having meta-oriented linkages, and wherein the plurality of acid monomers has at least 50 mole percent of the monomer containing aromatic group Ar2; and the second polymer has a structure derived from the reaction of metaphenylene diamine and isophthaloyl chloride. This fiber has use in heat-resistant protective apparel fabrics and garments. |
