    摘要： The present invention provides an N-phenylmaleimide compound that can improve the quality of the obtained copolymer by using N-phenylmaleimide containing impurities in specific amounts or less as at least one component of the copolymerization monomers. The N-phenylmaleimide compound of the present invention contains 0.1% by weight or less of N-(2,5-dioxo-1-phenyl-3-pyrrolidinyl)-N-phenylmaleamic acid (PPMA) and/or 0.3% by weight or less of N-phenylfumaramic acid (PFA).

    摘要： A method for the preparation of an acrylonitrile solution manifesting transparency, precluding coloration and opacification during the course of handling, and excelling in stability, is provided.
    The acrylonitrile solution of maleimide is such that, when it is subjected to a forced coloration test, the differences Δ L, Δa, and Δb values (invariably as absolute values) each between L, a, and b values before and after the test are respectively not more than 5, not more than 5, and not more than 10. The acrylonitrile solution of maleimide is prepared by purifying a crude maleimide; applying a primary antioxidant and a secondary antioxidant to the purified maleimide in the molten state; solidifying the molten maleimide by cooling; and subsequently dissolving the solidified maleimide in acrylonitrile.
