Table 3.

Molecular weights and binding constants determined as mol N-groups per dm³ for the studied PBAEs. These binding constants were converted to the binding constants per molecule by K_i′ = (average molecular weight of the polymer/molecular weight per N-group)×K_i. The values for PEIs are from reference [18].
