摘要
通过对低分子量聚碳酸酯熔融流变性能的测试,讨论了此类聚碳酸酯在流变曲线上不同于通用标准级聚碳酸酯的特殊性。并提出微量吸湿改变其流动类型和产生润滑作用的观点。此外,还测定了相应流动活化能,并对其变化趋势进行了初步说明。
A peculiarity of the flow curves was shown in comparison with that of general standard polycarbonate. It was advanced that trace moisture absorption could change the flow types and give the lubrication to the samples. In addtion, the change tendency of the flow activation energy was discussed initially.
