| Abstract: | It studied the influences of β crystalline form nucleator (amide compound) and peroxide on the mechanical properties and melt flowability of high MFR Z30S PP By means of WAXD diffraction,DSC analysis and polarizing microscope inspection,it showed that β crystalline form nucleator precipitated the creation of β crystalline form PP, and the spherulite of PP to be further fine-grainedThus,the impact strength of Z30S PP was improved |
