对SBR和NBR复合材料进行了热老化，研究了交联密度的变化。热老化后SBR复合材料的交联密度变化大于NBR复合材料。这可能是由烯丙基质子含量和苯基或腈基作为配体的锌配合物的作用。SBR复合材料的活化能略低于NBR复合材料。NBR样品达到50%和100%交联密度增加的寿命比SBR样品短。(C)2012年韩国工业与工程化学学会。Elsevier B.V.出版，保留所有权利。
SBR and NBR composites were thermally aged and the crosslink density changes were investigated. The crosslink density changes of the SBR composite after thermal aging were larger than those of the NBR one. This could be explained by the allylic proton contents and the role of phenyl or nitrile group as a ligand in a zinc complex. The activation energies of the SBR composite were slightly lower than those of the NBR one. The lifetime to reach 50 and 100% increase of crosslink density of the NBR sample was shorter than that of the SBR one. (C) 2012 The Korean Society of Industrial and Engineering Chemistry.
