Abstract
The kinetics of vapour sorption for DMF by films of methyl methacrylate-methacrylic acid copolymers (up to 21 mole% of the second component) have been found to give a peak on the kinetic curves which becomes rapidly smaller as the acid content increases. One can explain this effect on the basis of porometry as due to the mechanism of sorption by pores (channels) in combination with the relaxation rearrangement of the supermolecular organization of the copolymers.
