Abstract:The non-isothermal crystallization kinetics of polyoxymethylene （POM）
   and polyoxymethylene/co-polyamide （POM/COPA） at different cooling rates
   were investigated uisng differential scanning calorimetry （DSC）. The
   parameters of non-isothermal crystallization kinetics were obtained
   through Jeziorny, Ozawa, and MO methods. It showed that the increase of
   cooling rates made the crystallization peaks of POM and POM/COPA moved
   towards lower temperature and became wider. The addition of COPA
   increased the crystallization temperature and accelerated the
   crystallization rate. COPA played a role as a nucleating agent for
   non-isothermal crystallization of POM. Both Jeziorny and MO methods
   described this system very well.
