用核磁共振法研究了橡胶/炭黑共混物中聚合物链段的迁移率。顺式聚丁二烯和三元乙丙橡胶(EPDM)结合橡胶的自旋-自旋弛豫时间(T2)测量检测到至少两个弛豫区域:不动区域和相对自由区域。与纯胶相比,相对自由区域中的分子运动仍然受到限制。
The mobilities of polymer chain segments in mixtures of rubber and carbon black were investigated by nuclear magnetic resonance. Spin–spin relaxation time (T2) measurements oncis‐polybutadiene and ethylene–propylene–diene rubber (EPDM) bound rubbers detected at least two relaxing regions: an immobile region and a relatively free region. The molecular motions in the relatively free region are still constrained compared to those of the pure gum.
