摘要：
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.
