用X射线散射法研究了环氧化天然橡胶与环境友好型十二烷二酸交联后在循环拉伸过程中的应变诱导结晶（SIC）。取向参数的计算定量描述的非晶相在加载和卸载过程中的行为。与硫硫化橡胶的比较表明，SIC晶格参数是独立的交联的性质，并且出乎意料的交联密度影响结晶的发生。所揭示的SIC行为与这种可持续橡胶的良好机械性能有关。(C)2016爱思唯尔有限公司版权所有
Strain-induced crystallization (SIC) is studied in networks of epoxidized natural rubber crosslinked with eco-friendly dodecanedioic acid, by X-ray scattering measurements during cyclic stretching. An orientation parameter is calculated to quantitatively describe the behaviour of the amorphous phase during loading and unloading. Comparison with sulphur-vulcanized rubbers shows that SIC lattice parameters are independent of the nature of the crosslinks, and that unexpectedly the crosslink density affects the onset of crystallization. The revealed SIC behaviour is associated with the good mechanical properties of this sustainable rubber. (C) 2016 Elsevier Ltd. All rights reserved.
