摘要
采用粘度法测得了ＰＰＴＡ／ 尼龙－ １０１０ 分子复合体系在硫酸溶液中的粘度数据，作出了ηｓｐ ～ｃ′、［η］ ～Ｘｐ 及α～Ｘｐ 的关系曲线，显示ηｓｐ ～ｃ′与［η］ ～Ｘｐ 关系曲线都呈直线，α～Ｘｐ的关系曲线中，α＞ ０ ，表明ＰＰＴＡ 和尼龙－ １０１０ 在复合体系中是相容的，且在ＰＰＴＡ 含量为１０ ％ 左右，α值最大，表明其相容性最好。并从分子链结构方面，对组分间相容性进行了探讨。
The compatibility of PPTA/nylon-1010 molecular composite(MC) is determined by viscosity method. The plots of reduced viscosity(η\-\{sp\}/c') vs relative concentration (c') and intrinsic viscosity [η] vs composition (Xp) are linear. The interaction parameter α, calculated from parameter κ, [η] and Xp, are all >0. It is shown that PPTA and nylon-1010 molecules in PPTA/nylon-1010 MC are compatible within the whole composition range. According to the characteristic of the chain structure, the compatibility between PPTA and nylon-1010 molecules is discussed.
