  1. 较适宜的纺丝原液的浓度在14-16%,聚合物的比浓对数粘度为1.5-1.8,加工温度为50-70℃。

    The spinning solution would better with concentration of 14-16 % , inherent viscosity of polymer of 1.5-1.8 and processing temperature of 50-70 ℃ .

  2. 合成方法对共缩聚PPTA比浓对数粘度的影响

    Effect of synthesis process on reduced inherent viscosity of PPTA

  3. 封端剂苯甲酸、丙烯酸、α-甲基丙烯酸对产物收率、粘度、溶解性、颜色等的影响不大,产物收率在90%以上,比浓对数粘度在0.035~0.060dL/g之间。

    As the capping agent , benzoic acid , crylic acid and α - methacrylic acid do not largely affect the yield , viscocity , solubility and colourity . The yied was more than 90 % and the viscidity was in the range of 0.035 ~ 0.060 dL / g.
