研究了引发体系、聚合机理和聚合工艺对聚乙烯基吡咯烷酮残留单体的影响,通过条件优化和特殊工艺得到残留单体低于USP32所规定的0.01%以下的PVP K60制品。 The effects of initiator system, polymerization mechanism and polymerization process on the residual monomers of polyvinylpyrrolidone were studied. The PVP K60 product with residual monomer less than 0.01% as determined by USP32 was obtained through the optimization of conditions and special process.
