Table 1.

Comparison of the total work of adhesion (TWA), maximum detachment force (MDF) and improvement ratios (indicated polymer/corresponding unmodified polymer) of 30 mg tablets consisting of PAA-cysteine (100-, 250- and 450 kDa) and PAA-cys-2MNA (100-, 250- and 450 kDa) in comparison to corresponding unmodified polymers. Indicated values are mean ± S.D. of at least three experiments.
