K-18132/VA/CGM 366 Linear polymers Abstract Essentially linear polymers containing at least a proportion of structural units of the formula Ia or Ib Image (Ia). Image (Ib), which increases the solubility of the polymer in organic solvents and in which the aromatic rings are unsubstituted or substituted by one or more (C1-C4)alkyl groups, (C1-C4)alkoxy groups, phenyl groups or halogen atoms, X is a direct bond, -SO2-, -CO-, -CO-O-, -CO-NH- or - Image , and Y is a direct bond, -SO2-, -CO-, -O-CO-, -NH-CO- or Image in which R2 is a hydrogen atom or methyl, Q1 is -O-, -NR2-, -S- or -OCO-, and Q2 is -O-, -NR2-, -S- or -COO-, R1 is a divalent, aliphatic, cycloaliphatic, aromatic or araliphatic radical having up to 30 carbon atoms which is unsubstituted or substituted by one or more (C1-C4)alkyl, (C1-C4)alkylthio, (C2-C6)alkenyl, (C5-C12)cycloalkyl, or (C6-C12)aryl groups or by one or more cyano or nitro groups and in which one or more carbon atoms may be replaced by oxygen, sulfur and/or nitrogen atoms, or R1, if X and/or Y is a direct bond, is alternatively -CO-, can advantageously be processed from solution and are suitable for modifying matrix resins.
