The influence of the interaction of gelatin with a protected 
formaldehyde tanning agent on the rheological parameters of interphase 
adsorption layers formed at the interface of a 0.1% aqueous solution 
of gelatin-metaxylene has been investigated as a function of the 
mass-molecular distribution of initial gelatins. It has been shown 
that the chemical modification of gelatin with tanning agents weakens 
the process of gel formation in the interphase layer directly with 
the depth of the tanning process. This dependence is the most pronounced 
for gelatin with a high content of fractions with a molecular mass 
of more than 285 kDa.
