K-18064/A/CGM367 Essentially linear polymers Abstract of the disclosure Essentially linear polymers having a reduced viscosity of from 0.1 to 2.0 dl/g, measured on a 1 % by weight solution in N-methylpyrrolidone (NMP) at 25°C, and containing at least a proportion of structural units of the formula I Image (I), in which the aromatic rings are unsubstituted or substituted, Ar is a divalent aliphatic, cycloaliphatic, araliphatic or aromatic radical having up to 50 carbon atoms, X1 is a direct bond, -SO2-, -CO-, -CO-O-, -CO-NH- or Image in which R2 is a hydrogen atom or methyl and Q1 is -O-, -NH-, -S- or -OCO-, Y1 is a direct bond, -SO2-, -CO-, -O-CO-, -NH-CO- or Image in which R2 is a hydrogen atom or methyl and Q2 is -O-, -NH-, -S- or -OCO-, R1 is a divalent aliphatic, cycloaliphatic, aromatic or araliphatic radical having up to 30 carbon atoms, which increases the solubility of the polymer in organic solvents can advantageously be processed from the solution and are suitable for modifying matrix resins.
