Stress-strain relations and strain-induced crystallization (SIC) of unvulcanized and vulcanized states of natural rubber (NR) and synthetic polyisoprene (IR) were studied using synchrotron X-ray at various temperatures from -50 to +75 °C. Unvulcanized IR is a polymer melt that shows a viscous respon...
