چکیده مقاله:
In this study peroxide was added to polypropylen (PP) and peroxide/PP was compounded during extrusion. in extruder and process of controlled rheology pp , polypropylene melt flow index (MFI) increased from 0.3 to 12 grams per 10 minutes. In addition to peroxide, 5% talc, 0.3% PP maleic compatibilizer,and thermoplastic vulcanizates (TPV) impact modifier also were added to PP(60 R). desirable physical and mechanical properties were attained by using these materials.In this study peroxide was added to polypropylen (PP) and peroxide/PP was compounded during extrusion. in extruder and process of controlled rheology pp , polypropylene melt flow index (MFI) increased from 0.3 to 12 grams per 10 minutes.
