**Abstract**
 The influence of a rare-earth coupling agent (RE) on the non-isothermal crystallisation behaviour of PP was studied by differential scanning calorimetry. Experimental results showed that use of RE caused a decrease in the crystallisation temperature, melting temperature and crystallinity of PP in WF/RE/PP compared with those in WF/PP. The Avrami, Ozawa and Mo methods were used to describe the crystallisation process. The Avrami and Ozawa methods neglected the secondary crystallisation and followed primary crystallisation. The Mo approach could successfully describe the overall crystallisation process. The relation of the half times of crystallisation (t1/2) of the three samples, t1/2(WF/PP) < F(T)(WF/RE/PP)
