    It was found that the grafting yield was increased with dose up to 40kGy, but decreased with dose rate from 50 to 500 Gy/min.
    但随剂量率的增加(50~500Gy/min),接枝率反而下降。
    The grafting yield higher than 80% could be obtained when the grafting reaction was proceeded at 25-30℃ within 10minutes after 10kGy irradiation.
    淀粉预辐照的吸收剂量约10kGy,辐照后 10min内在 25~30℃下进行接枝可以获得 80%以上的接枝率。
    Electron beam coirradiation induced graft polymerization has been carried out in air between methyl methacrylate (MMA) and anataseand rutileTiO2 nanoparticles, respectively. The results show that the grafting yield of ATiO2 (10.5%) is larger than that of RTiO2 (6.1%), owing to its high specific surface area.
    锐钛矿和金红石型纳米TiO2(A-TiO2和R-TiO2)分别与甲基丙烯酸甲酯(MMA)在空气中进行电子束共辐射接枝聚合,结果表明A-TiO2接枝率(10.5%)高于R-TiO2(6.1%),被认为是由于A-TiO2具有较高的比表面积造成的。
    When the grafting yield is smaller than 5.98%, both the pH-responsiveness coefficient and the pH-responsive gating factor of membrane pore size increase with increasing the grafting yield;
    接枝率≤5.98%时,pH感应开关系数和膜孔径感应pH变化倍数均随接枝率的增加而增加;
    The grafting yield was in the range of 150% -250% when the volume fraction of the monomers was 20% -25% and the co-irradiation dose was 1.2-1.8 kGy/h.
    当单体体积分数为20%-25%,辐射剂量率为1.2~1.8 kGy/h时,接枝率 可以控制在150%~250%。
    The results show that the grafting yield is higher and the mechanical strength is better when the dose rate is(0.5) kGy/h~(1.0) kGy/h,co-irradiation time was 5 h~8 h,and divinylbenzene content is 2%.
    结果表明,共辐照接枝反应中,当二乙烯苯含量2%,剂量率0.5 kG y/h~1.0 kG y/h,照射时间5 h~8 h时,接枝纤维的接枝率和力学强度较高。
