采用力学光谱法、差示扫描量热法和广角x射线散射法研究了N-三烷基硅己内酰胺（SL）含量不同的n6型聚酰胺的物理行为。共聚物是在等温条件下通过阴离子本体聚合得到的。酰胺基氮原子上的大取代基的存在对氢键的数目以及物理化学键的形成起着至关重要的作用。这种键导致改性聚酰胺的物理行为发生重大变化。这些变化已经被研究过了。
The physical behavior of polyamides of type N 6 with different contents ofN-trialkylsilylcaprolactam (SL) has been investigated by mechanical spectrometry, differential scanning calorimetry and wide-angle X-ray scattering. The copolymers have been obtained by an anionic polymerization in bulk under isothermal conditions. The presence of a bulky substituent at the nitrogen atom of the amide group plays an essential role for the number of the hydrogen bonds as well as for the formation of physical and chemical bonds. This bonds results in significant changes of the physical behavior of the modified polyamides. These changes have been studied.
