Abstract
Low-density polyethylene (LDPE)/styrene-butadiene rubber (SBR) thermoplastic vulcanizates (TPV) were prepared by dynamic vulcanization, and the non-isothermal crystallization kinetics of the LDPE/SBR TPV and pure LDPE were investigated by differential scanning calorimetry (DSC), and the crystallization processes of LDPE/SBR TPV and pure LDPE were depicted by the Avrami, Ozawa and Mo equation models. The findings indicated that the crystallization behavior of both LDPE/SBR TPV and pure LDPE can be described by the Mo model and Avrami model modified by the Jeziorny correction, while the Ozawa model was not applicable to describe the behavior. Kinetic data analysis showed that LDPE/SBR TPV had higher crystallization onset temperature (T0), peak crystallization temperature (Tp), and more stable crystallinity compared to pure LDPE at the same cooling rate.
