The effects of polymer structure and composition on radioinduced changes in water-soluble polymers were studied by using 0.22% solutions of PVA and PVAAc irradiated with Co/sup 60/ at 6.6 x 10/sup 4/ hr in air and at room temperature. The degree of main chain scission increased linearly with the irradiation time. The G-value was larger for the diluted PVAAc than for the PVA, but the G value of cross-linking of the concentrated solution was smaller for PVAAc than for PVA. Therefore, it was concluded that both the rates of degradation and cross-linking for PVA in aqueous solution depended largely upon and were approximately proportional to the amount of vinyl acetate unit in its polymer chain.
