Abstract: Cold crystallization process of N-(1-naphthyl) succinimide below glass transition temperature was monitored by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The results showed that the kinetic curve of cold crystallization was completely different from that of melt crystallization, exhibiting "fast-slow-fast" three increasing stages. This result could be explained in terms of low-density-interface nucleation and volume-contraction effect.
