| titleOfInvention | Polybenzoxazole amides, esters and thioesters, polybenzthiazole amides, esters and, thioesters and preparation thereof |
| abstract | The invention comprises an aromatic polyamide polymer having oxy-or thio- groups in ortho or peri relationship to the amide structural units which can be cyclised to form benzoxazole or benzthiazole structural units by heating, and -CONH-, CO.0- or CO.S- structural units which are not able to cyclise at the temperature at which the benzoxazole or benzthiazole units are formed. Such a polymer is prepared by reacting (A) 9 polybasic carboxylic aromatic acid or a functional derivative thereof, with (B) a bis o-amino thiophenol or a functional derivative thereof, with (B) a bis o-amino phenol or a bis o-amino thiophenol or a functional derivative thereof and (c) a third component of formula: |
