摘要/Abstract

摘要： 用脉冲谱仪在室温下测量了不同链节结构的聚丁二烯固体核磁共振氢谱,谱图的差异明显可见。报导了由星型支化样品核磁共振谱分解得到的二个洛伦茨峰的化学位移及强度参数的温度依赖关系。
通过测量掺入不同性质炭黑的高顺聚丁二烯样品的FID信号与温度的关系,研究了炭黑与橡胶的相互作用,实验结果表明,不能肯定炭黑对橡胶补强作用的"双壳层模型"。很可能这种补强作用是由于炭黑的加入产生的相分散均匀化的结果,

Abstract: The ¹H NMR Spectra were measured using a pulsed spectrometer at room temperature for solid polybutadiene samples with different chain structure. They are quite distinguishable between each other.The temperature dependence of the chemical shifts and intensity radio of the two decomposed Lorentzian peaks for the star-type branched polybutadienc are reported.
An investigation to carbon black rubber interaction were carried out with high cis-polybutadiene samples added different types of carbon black by measuring EID'S temperature dependence. The results fail to confirm the so called "double layer model", and suggest an homogenization effect on the phase distribution.
