不同分子量初生态尼龙1010的熔融

On the Melting of the Nascent State Nylon 1010 with Different Molecular Weights

利用ＤＳＣ方法研究了熔体聚合不同分子量初生态尼龙１０１０样品的熔融，发现随分子量增大，熔点有极大值，高规整性晶体的量也呈极大值，且两者峰值相同；结晶度则逐渐减小；熔融热、熔融熵也逐渐减小；其原因主要是高规整度晶体量减少所致。

The melting of the nascent state nylon 1010 samples melt condensation polymerized with different Mη have been studied by DSC.The relations of melting point, content of higher order crystal with Mη are similar,the plots like a peak, at Mη=1.48×104 have the maximum.The melting heat, melting entropy and crystallinity are decreased gradually with Mηincreasing.
