摘要:
The invention relates to a fiber, pulp, fibril, or fibrid comprising polybenzazole having a repeating unit of formula (I) or (II) wherein Ar1 and Ar2 are independently an aromatic group having 4 to 12 carbon atoms, Ar1 has the para configuration and 40-100% of the repeating units are repeating unit I and/or repeating unit II and wherein the polybenzazole contains less than 1500 ppm of non-extractable phosphorus compound if 100% of the repeating units are repeating unit I and/or repeating unit II and X and Y are the same. The method allows the manufacture of phosphorous element free a fiber, pulp, fibril, or fibrid containing said polybenzazole precursor or polybenzazole and a spinning method for obtaining said fiber, pulp, fibril, or fibrid.
