PROCESS FOR PREPARING VINYLPYRROLIDONE POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a process for preparing a vinylpyrrolidone polymer which process is capable of initiating the polymerization for vinylpyrrolidone at a lower temperature and polymerizing it for a shorter time and also reducing an amount of the remaining vinylpyrrolidone. SOLUTION: The process comprises a polymerization of a vinylpyrrolidone using a polymerization initiator of hydrogen peroxide and an ammine complex salt with copper.
