Latest Patent Applications
Lei Niu's latest patent application is titled "Polymerization Inhibitor for N-Vinyl Pyrrolidone Monomer and Use Thereof." This application discloses a polymerization inhibitor that is selected from an inorganic weak acid potassium salt and/or an organic acid potassium salt. The polymerization inhibitor is added to N-vinyl pyrrolidone monomers and is sealed and preserved under the protection of inert gas. The addition amount of the polymerization inhibitor is specified to be between 0.005-0.2% by mass with respect to the mass of the N-vinyl pyrrolidone monomers. This innovative approach effectively inhibits the self-polymerization of the N-vinyl pyrrolidone monomers, thereby extending their shelf life. Additionally, the chromaticity and toxicity of the monomers can be significantly reduced. The polymerization inhibitor can be used directly during solution polymerization without being removed, ensuring that it does not affect the chromaticity of the polymerization solution.
Conclusion
Lei Niu's work exemplifies the innovative spirit in the field of polymer chemistry. Her research on polymerization inhibitors is poised to make significant contributions to the stability and safety of chemical applications.
