In this paper, effect of ethylene glycol dimethyacrylate (EGDMA)on radiation reactions of random 1,2-polybutadilene (1, 2-PB)was researched. In order to get information on radiolytic changes in 1,2-PB, the Sol fraction, the converation of double bonds, the structure chang of the irradiated sample were measured by using IR and ,1,H-NMR techniques. The results show that random chain process of crosslinking in irradiation is not changed by the presence of EGDMA in 1,2-PB; its G(c. 1) and G(Ⅰ) Value increases with increasing of the ratio of EGDMA to 1,2-PB in the system, while its G(-V) and G(cy) deacreases with that. In presence paper, the mechanism of effect of EGDMA on radiation reactions of 1,2-PB was also discussed.
