FAQ - 기술 및 공급 관련 문의

• 질문:

  What is N-Phenylmaleimide CAS 941-69-5?

  답변: N-Phenylmaleimide, also called PMI, NPMI, or 1-phenyl-1H-pyrrole-2,5-dione, is a maleimide monomer with the molecular formula C10H7NO2 and molecular weight 173.17 g/mol. Its EC number is 213-382-0, and it is commonly supplied as a yellow crystalline solid for polymer modification and specialty synthesis.
• 질문:

  What is N-Phenylmaleimide used for in polymer materials?

  답변: It is mainly used as a heat-resistant modifier for ABS, PVC, PMMA, and other thermoplastics. It can also act as a reactive maleimide monomer in copolymers and as a crosslinking or vulcanization modifier in rubber systems, improving rigidity, heat distortion temperature, thermal stability, and chemical resistance.
• 질문:

  How does N-Phenylmaleimide improve heat-resistant ABS?

  답변: N-Phenylmaleimide introduces rigid imide and phenyl groups into the polymer backbone, increasing chain stiffness and heat resistance. It can be copolymerized with styrene, acrylonitrile, maleic anhydride, or blended as an N-PMI-modified copolymer, allowing formulators to raise HDT while retaining processability.
• 질문:

  How is N-Phenylmaleimide synthesized?

  답변: A common route is the reaction of maleic anhydride with aniline, first forming the intermediate amic acid and then closing the imide ring through dehydration/imidization. The resulting maleimide monomer can then be copolymerized with other vinyl monomers in solution, emulsion, or bulk polymerization systems.
• 질문:

  How should N-Phenylmaleimide be stored and handled?

  답변: Store it in a cool, dry, well-ventilated area with containers tightly sealed to prevent moisture pickup and contamination. Avoid contact with strong oxidizing agents and sources of ignition, and follow standard handling practices for reactive polymer intermediates.
