| Abstract: |
| The non-isothermal crystallization behavior of PP in three types of NBR/PP thermoplastic vulcanizates (TPVs) was investigated by differential scanning calorimetry method,and the Ozawa model and Mo Zhi-shen equation were also used to analyze the non-isothermal crystallization process. The results showed that,NBR acted as heterogeneous nucleation centers of PP nucleus, the crystallization rate of PP thereby accelerated;and the TPV prepared by in situ reactive compatibilization had the highest crystallization rate.Non-isothermal crystallization kinetics fitted Mo Zhi-shen equation well. |
