Process for producing N-vinyl lactam polymer and N-vinyl lactam polymer

摘要

PROBLEM TO BE SOLVED: To provide a method for producing N-vinyllactam polymers, making it possible to conveniently produce N-vinyllactam polymers with a low molecular weight, while suppressing the generation of by-products.SOLUTION: A method for producing N-vinyllactam polymers includes the step of reducing the molecular weight of N-vinyllactam polymers in the presence of hydrogen peroxides.SELECTED DRAWING: None
