摘　　要：采用变温红外光谱研究了尼龙1216的Brill转变并测得Brill温度约为150℃。一些α谱带在转变过程中消失,氢键强度也急剧减弱。这些现象证明了Brill转变的“局部熔融”机理。Brill transition in nylon 1216, a long alkane segment nylon, was studied by variable-temperature FTIR. The results show that nylon 1216 undergoes Brill transition at about 150℃. During the transition, some ' α bands' disappeared and the intensity of hydrogen-bond decreased dramatically, which support the 'local melting mechanism' for the transition.
