“…Although the general mechanism is thought to be the same, the crystallinity is typically lower in synthetic isoprene rubber [11,12,3]. This suggests that the natural network in NR, formed by proteins and lipids being attached to functionalized chain ends, supports the formation of crystallites [39,40,41]. Lipids are thought to be the main factor rather than proteins [42,43].…”

“…The stretch ratio value selected was based on two premises: high enough to be close to the ultimate strain, but low enough so as to be on the limit of the strain induced crystallization of the rubber. 15,16 The initial free length between the clamps was 40 mm. No visible damage was detectable after the cyclic deformation.…”

Broadband dielectric spectroscopy (BDS) is introduced as a new and powerful technique to monitor network and macroscale damage healing in an elastomer. For the proof of concept a partially cured sulfur-cured natural rubber (NR) containing reversible disulfides as the healing moiety was employed. The forms of damage healed and monitored were an invisible damage in the rubber network due to multiple straining and an imposed macroscopic crack. The relaxation times of pristine, damaged and healed samples were determined and fitted to the HavriliakNegami equation to obtain the characteristic polymer parameters. It is shown that seemingly full mechanical healing occurred regardless the type of damage, while BDS demonstrates that the polymer architecture in the healed material differs from that in the original one. These results represent a step forward in the understanding of damage and healing processes in intrinsic selfhealing polymer systems with prospective applications such as coatings, tires, seals and gaskets.

“…Because of the poor crystalline nature of rubber materials, it has been a tricky problem to give a comprehensive study on the crystalline behavior of rubber even that calorimetry 1 and XRD 2 has long been applied to characterize the crystallization behavior. However, in recent years with the great progress of synchrotron X-ray diffraction (SXRD), it is possible to observe the crystalline behavior of rubber in situ due to the high diffraction intensity of synchrotron radiation.…”

“…[2][3][4][5][6][7] Among them, the studies on natural rubber (NR) or its synthetic analog related studies have been most successful and explicit. [2][3][4][5][6] Besides, Toki et al 7 have undertaken some primary study on general purpose synthetic rubbers such as butadiene rubber (BR), butyl rubber (IIR). However, to our best knowledge, the analogous work on comprehensive crystallization behavior of polychloroprene rubber (CR) combined with SXRD has not been undertaken yet.…”

The crystallization behavior of polychloroprene rubber (CR) has been studied in this work. Differential scanning calorimetry (DSC) was applied to characterize the crystallization behavior. And X-ray diffraction was applied to determine the impact of crosslinking on the crystallization of CR. Synchrotron X-ray diffraction (SXRD) method was applied to study the dynamic crystalline behavior. On the basis of the experimental results, it is found that crosslinking will hamper the crystallization of CR while large strain can restore this course. And this is in accord with the Mooney-Rivlin analysis result. Detailed discussion was offered circling around this phenomenon.
