质子自旋-自旋弛豫时间的测量已在300和400 MHz的约束橡胶填料混合物，从溶剂萃取的二氧化硅填充和silicafilled-modified聚丁二烯，一方面，炭黑填充和炭黑填充-modified丁苯橡胶，另一方面。两个弛豫时间观察到的所有样品。它们分别归因于紧密和松散结合的橡胶组分的发生。讨论了填料的接枝改性对粘合胶及其两组分形成的影响。John Wiley & Sons，Inc.
Proton spin–spin relaxation time measurements have been performed at 300 and 400 MHz on bound rubber-filler mixes resulting from the solvent extraction of silica-filled and silicafilled-modified polybutadiene, on the one hand, and of carbon black-filled and carbon blackfilled-modified styrene butadiene rubber, on the other hand. Two relaxation times are observed for all samples. They are ascribed to the occurrence of tightly and loosely bound rubber components, respectively. The effect of the grafting modification of the fillers on the formation of bound rubber and its two components is discussed. © 1992 John Wiley & Sons, Inc.
