2.
The factors that may cause degradation of poly(p-phenylene terephthalamide)(PPTA) during preparation were studied by measuring the inherent viscosity.
通过测量不同条件下聚对苯二甲酰对苯二胺(PPTA)溶液的比浓对数黏度,分析在PPTA纺丝前可能引起聚合物降解的因素,这些因素包括纺丝液浓度、残余的CaCl2、N-甲基-2-吡咯烷酮、水分和氢氧化钙等,最终得到水分和氢氧化钙对PPTA的降解影响很大,其余影响较小的结论。

补充资料：对数平均浓度差
分子式：
CAS号：
性质：指传质过程中两端点(传质设备前后)浓度差ΔCa、ΔCb的对数平均值ΔClm=。当平衡线及操作线均可视为直线、总传质系数可取为常数时，△Clm即为传质过程的平均推动力。
