Abstract
Abstract The Flory's model for high polymers is based on the assumption that the final stretched state is achieved by two separate steps: stretching and strain-induced crystallization (SIC). This assumption is valid in fast stretching process, where SIC cannot occur instantaneously. We check if Flory's assumption can influence the equilibrium crystallinity of SIC ( C e ) for different elongation rates in natural rubber (NR). It is found that the C e is independent on the elongation rate. Thus, the calculation of C e in Flory's model is valid for all the equilibrium states of different elongation rates, not to be limited by the Flory's assumption. Furthermore, the calculated C e in Flory's model is used to calculate the elastocaloric temperature change (Δ T ), which agrees with the directly measured one. It can meet the theoretical requirement for the new potential cooling application of NR.
