ABSTRACT OF THE DISCLOSURE A basic copolymer whose main chain is cross-linked which comprises about 6 to about 98 % by weight of recurring units of Formula (A) or (B), Image (A) or Image (B) wherein R1, R2 and R3, which may be the same or different, each represents a hydrogen atom or a hydrocarbon group selected from the group consisting of C1-20 alkyl groups, C3-10 cycloalkyl groups, C3-8 alkenyl groups, C6-15 aryl groups, C7-12 arylalkyl groups and C1-15 aminoalkyl groups; and X is an acid radical, and about 2 to about 94 % by weight of cross-linked units based on the total weight of the recurring units of Formula (A) or (B) and the cross- linked units and, if desired, up to about 92 % by weight of units of a monoethylenically unsaturated monomer or a conjugated monomer based on the total weight of the recurring units of Formula (A) or (B), the cross-linked units and the units of the monoethylenically unsaturated monomer or the conjugated monomer.
