摘要：Claimed is a rigid rod polymer in which at least 50 % of the recurring groupssatisfies the formula (I) and, optionally, in the remaining groups the 2,5-dihydroxy-p-phenylene is replaced by an arylene which may be substituted or not, and/or the
pyridobisimidazole is replaced by benzobisimidazole, benzobisthiazole, benzobisoxazole,pyridobisthiazole, and/or pyridobisoxazole. A 10-21 wt.% solution of the polymer inpolyphosphoric acid can be spun into fibres having exceptional properties.
