摘 要: 用红外光谱法研究了PA1010/66共聚物氢键含量、N—H键伸缩振动力常数分布与组成的关系,发现66盐重量含量为40%时氢键含量最低,N—H伸缩振动力常数分布最宽,解释了PA1010/66共聚物热力学、结晶、机械等性能随组成改变而变化的原因. It is investigated that the realations between the hydrogen bond(HB) contents, the distribution of the force contant of N H bond expansion vibration and the copolymer compositions of 1010/66 copolyamides by IR spectra. The result shows that the HB content is the lowest and the distribution of the force contant of N H bond expansion vibration is the widest when 66 amide content is 40 %wt (~50%mol). From the results, the changing reasons of the thermodynamic, crystallization and mechanical properties of the copolymers with the compositions have been explained.
