摘要
Abstract
Blends of polyoxymethylene and thermoplastic polyurethane(POM/TPU)were prepared by melting blending through Brabender single screw extruder. Non-isothermal crystallization kinetics and spherulite morphology of POM/TPU blends were characterized by differential scanning calorimeter(DSC)and hot stage polarizing light microscopy(HS-PLM), respectively. It is found that non-isothermal crystallization kinetics of POM/TPU blends analysed with Mo’s equation and Jeziorny method achieved the same result. Homogeneous nucleation and heterogeneous nucleation both existed during crys-tallization,with indicates TPU accelerated the crystallinity of POM slightly.关键词
