摘　　要：通过对引发剂、活化剂、温度、pH等因素的研究,总结出一种制备超低分子量超低残单聚N-乙烯基吡咯烷酮的新方法。采用该方法制备的聚N-乙烯基吡咯烷酮,分子量在2000~10000之间,而且具有较窄的分子量分布和非常低的残余单体,可以满足各领域的要求。Based on the study on factors such as initiator, activator, temperature and pH, a new method for the preparation of polyvinyl pyrrolidone with ultra-low molecular weight and ultra-low residue monomer has been sum marized. The molecular weight of polyvinyl pyrrolidone prepared by this method is between 2000-10000, it has rel- atively narrow molecular weight distribution and extremely low residual monomer which can satisfy the demand in various fields.
