Polybenzazoles fibres

Polybenzazole fibre group polybenzimidazole and polybenzoxazole fibres... 

Each of these major fibre groups has been described in detail elsewhere"- and so their major features only are presented below. They may be divided into the following the thermosets, the aramids and arimids, the polybenzazoles, and the semicarbons. Not only are the generic chemistries similar within each grouping but their properties and potential application suitabihties are similar.
