    • Viruses are selectively separated from an aqueous mixture of virus and nonviral protein by contacting the aqueous mixture with a water-insoluble polyelectrolyte polymer containing basic groups to selectively sorb the virus on the polymer and then if desired removing the polymer containing the virus from the aqueous mixture. The polyelectrolyte polymers are polycationic or polyampholytic in nature and contain imide groups selected from the group consisting of diloweralkylaminoloweralkylimide groupings and loweralkyliminodi(loweralkylimide) linkages as exemplified by crosslinked dimethylaminopropylimide derivatives of isobutylene/maleic anhydride copolymers.
    • 通过使含水混合物与含有碱性基团的水不溶性聚电解质聚合物接触,将病毒和非病毒蛋白质的水性混合物选择性地分离,以选择性地吸附聚合物上的病毒,然后如果需要,从含水混合物中除去含有病毒的聚合物 。 聚电解质聚合物本质上是阳离子或聚阴离子的,并且含有选自二异丁烯基氨基低级烷基亚胺基和低级烷基亚氨基(低级烷基亚胺)键的酰亚胺基,如异丁烯/马来酸酐共聚物的交联二甲基氨基丙基酰亚胺衍生物所示例。
