研究了不同体系硫化天然橡胶的网络拓扑结构对其高温拉伸强度的影响。天然橡胶在高应变下的抗拉强度是由拉伸时的结晶能力决定的。该性质随温度和交联密度的变化不仅与交联的性质有关，而且与交联的空间分布有关。在这个意义上，环己烷在橡胶基体中的凝固点下降的测量被用来评价交联的空间分布。©2005 Wiley期刊公司应用化学学报，2009,31 (2):444 - 444
The influence of network topology on tensile strength at elevated temperature of natural rubber compounds vulcanized with different systems was studied. The tensile strength behavior of natural rubber at high strain is attributed to the capacity to crystallize on stretching. Variation of this property with the temperature and/or crosslink density was related, not only with the nature of the crosslinks, but also with their spatial distribution. In this sense, measurements of the freezing point depression of cyclohexane imbibed in the rubber matrix were used to evaluate the spatial distribution of the crosslinks. © 2005 Wiley Periodicals, Inc.
