چکیده مقاله:
In This research Talc As a nucleating agent, at mass (2000ppm, 4000ppm, 6000ppm, 8000ppm, 10000ppm) was added into isotactic polypropylene (IPP) matrix by solution/precipitation method and compression-molded method. The crystallization morphology, was studied by scanning electron microscope (SEM), Talc particles well dispersed in matrix polypropylene. The result showed that talc can induce α crystal and increase the degree of crystallization of IPP,. As well as talc well dispersed in polypropylene matrix. The melting peak of IPP analyzed by differential scanning calorimetry (DSC) was raised. It explains that crystalline perfect degree of PP were increased. Mechanical properties of IPP, which were measured by use of izod impact test, tensile properties,flexural modulus were improved. And the optimal amount of nucleating agent was 10000ppm
