Abstract: The kinetics of swelling of thermoxidized fractions of natural rubber in
benzene was studied by measuring volumetrically the amount of incorporated
solvent in a thin plate of the investigated sample. It has been found that the
mean integral diffusion coefficient of benzene in a solid film of natural rubber
varies with the time of destruction according to the equation D = D0 ek1t , where
D0 is the value of D in the nondestroyed sample and k1l is an empirical constant.
The thermal oxidation was carried out at 130°C.
