Using dicumyl peroxide as initiator and styrene-divinylbenzene blend as cross-linking agent,the crosslinking and grafting polypropylenes( PPs) were prepared by reactive extrusion. The melt strength,processability and crystallization behaviors of PPs were investigated by the melt flow rate,dynamic rheology and differential scanning calorimetry measurements. The effect of the components on the structures and properties was also studied. The results indicate that the additions of the moderate dicumyl peroxide,...
