摘要：
Isothermal and non-isothermal crystallization kinetics of cis-1,4-polyisoprene(CPI) /trans-1,4-pol- yisoprene(TPI) binary blends were investigated by differential scanning calorimetry method. The results were analyzed by Avrami equation and MO theory. It was found that the presence of CPI suppressed the crystallization rate of TPI component during both isothermal and non. isothermal crystallization. The crystallinity of TPI component was enhanced by CPI during the isothermal crystallization. For non-isothermal crystallization, the relative content of beta crystal form increased, while the crystallinity of TPI component changed little with the incorporation of CPI component.
