“…During the stretching process, molecular chains can slide relatively, and the ability of molecular chains to combine into microcrystals is controlled by the stretching process. 17 Compared with U-CR, A192-CR is crosslinked by double bonds and dechlorinated, which leads to the decrease of its structural regularity and the decrease of the number of orientable free crystallizable chains. The relative molecular weight between crosslinking points decreases with the increase of crosslinking density.…”

“…The unit cell of polychloroprene is orthogonal, with four polymer chains passing through and parallel to the c‐axis, 5 which is oriented in the direction of stretching, and belongs to the class of strained crystalline elastomers. During the stretching process, the rubber molecular chains stretched and transition from folded to stretched conformation, resulting in strain‐induced crystallization (SIC) 15–17 . SIC is closely related to the fracture strength and fatigue fracture resistance of rubber 10,18,19 .…”

“…A first important point is that crystal structures are in general similar for QC and SIC [8][9]. QC in elastomers that readily strain-crystallize is quite often a slow process even at optimal degrees of super-cooling, and crystallization half-times are counted in hours or days [10][11]; folded conformation is most probable and spherulitic or lamellar growth is observed under some conditions [6][7][8]. The crystallization kinetics progressively accelerate with increasing applied elongation and crystallites become oriented with the chain-axis on average parallel to the stretching direction [11,[15][16][17].…”
