    Abstract: Acrylic fiber is manufactured by wet-spinning a mixed polymer solution consisting of 80-98wt% acrylonitrile polymer solution and 2-20we% urea polymer solution. The urea polymer is in-situ polymerized by the polycondensation of diamine compound having a molecular weight of less than 300, or diamine-diol compound, with diisocyanate compound, in the acrylonitrile polymer solution containing more than 85wt% acrylonitrile monomer. The produced acrylic fiber shows an excellent dimension stability.

    Abstract translation: 通过将由80-98重量%丙烯腈聚合物溶液和2-20重量%尿素聚合物溶液组成的混合聚合物溶液进行湿式纺丝来制造丙烯酸纤维。 通过在分子量小于300的二胺化合物或二胺 - 二醇化合物与二异氰酸酯化合物的缩聚反应将脲聚合物原位聚合在含有85重量%丙烯腈单体的丙烯腈聚合物溶液中。 生产的丙烯酸纤维显示出优异的尺寸稳定性。
