摘要：
The effects of reaction factors on the composition in network-modified polypropylene (PP) were studied. The chemical reaction between functionalized polypropylene and polyester (PES) was characterized with infrared analysis. Phase separation between these two components is reduced as a result of the chemical crosslinks and physical entanglement. The mechanical properties of the blends are improved due to the amelioration of compatibility. The result of ESR shows that 2A(zz) reaches its maximum value at a ratio of 87/13 for PP/PES. At the same time, the temperature at which fast movement of the molecule begins comes up to 290K.
