摘　　要：报道了 N ,N -亚甲基双丙烯酸酰胺 ( N ,N -MBAA)在 60 Co-γ射线下辐照效应 .对不同辐照条件下的双键含量变化进行了测定 .同时讨论了固态 N,N -MBAA和 N,N -MBAA水溶液经辐照后的结构的变化 .实验结果表明 ,固态 N,N -MBAA在较高温度下辐照易聚合 ,因此辐射敏化反应 PVA纤维应在常温下进行辐照 .The effects of 60 Co-γ irradiation on N,N-methylenebisacrylamide were studied. The fragments having double bond under irradiation were measured. Effects of radiation on the structure of the solid N,N-methylenebisacrylamide and its aqueous solution had been discussed. Experiment results show that N,N-MBAA is easily polymerized at relative high temperature, so that radiation-induced crosslinking of PVA in the presence of irradiated N,N-MBAA should be carried out at room temperature.
