      Use

      From the structure, we can find it is a quinary cyclic monomer with the structure of 1,2-disubstituted vinyl. Embed it into polymer chain can improve the polymer chain internal rotation resistance to increase polymer heat resistance.
      N-PMI is divided into monomer can polymer. The monomer is mainly used in the production of resin modifier (N-PMI polymer). The N-PMI polymer can be used as vulcanization cross-linking agent in natural and synthetic rubber, heat resistant modifier in ABS, PVC, PMMA and photographic material. It can improve the heat resistance, impact resistance, hot melt and processability of resin. It can also be used as resin intermediate to produce heat resistant polymer, plant growth accelerator and other agrochemicals. Besides, it has certain antibacterial activity to be used as marine equipment anti-fouling agent, etc.
