When the PVA film is irradiated in CCl 4 , PVA is swollen and crosslinked. A Phenomenological theory is proposed for this experiment. The processes are considered that with the change of diffusion constant CCl 4 enters into PVA as the radiation dose increases, and the radicals from CCl 4 react upon PVA and cause crosslinking. The results of calculation agree reasonably with experiments, that is, the weight changes of swollen polymers against the total dose, the gel fraction changes and the… CONTINUE READING
