Abstract: A polyimide moulding (esp. fibre or film) contains repeating units (I); where Q1 and Q2 are aliphatic, alicyclic or aromatic (monocyclic or fused or unfused polycyclic) groups, Q1 being bivalent and Q2 tetravalent. At least 85% (molar) of (I) are units of formula (II) and 0.5-15% are units of formula (III), (IV) and/or (V). Specifically, R1 is 2-10C alkylene, -B-C6H4-A-, naphthylene, anthracenylene, -C6H4-X1-C6H4-, -C6H4-CMe2-C6H4-O-C6H4-Z1-C6H4-O-C6H4-CMe-C6H4-; A and B are 0-5C alkylene; X1 is a direct bond, CH2, CMe2, -C(CF3)2-, S, O, SO, SO2, CO, -O-C6H4-O-, -O-(p)C6H4-C6H4-(p)C6H4-O- or -O-(p)C6H4-Y1-(p)C6H4-O-; Y1 is a direct bond, CMe2, C(CF3)2, S, O, SO, SO2, CO, -CO-C6H4-CO-, -O-C6H4-O-, -O-C6H4-SO2-C6H4-O-, or -O-C6H4-CO-C6H4-O-; Z1 is a direct bond, CMe2, C(CF3)2, S, O, SO, SO2 or CO. R2 is e.g. (VI), (VII), etc. X2 is a direct bond, O, S, SO, SO2, CH2, CO, CMe2, C(CF3)2, -O-C6H4-O-, -CO-C6H4-CO- or -O-C6H4-Y2-C6H4-O-; Y2 is a direct bond, O, S, SO, SO2, CH2, CO, CMe2 or C(CF3)2.
