Melt-mixed polyblends of high-density polyethylene (HDPE) and an ethylene-propylene copolymer (EPM) containing 78 mol% ethylene were studied in the complete composition range, using quenched and annealed samples. Phase contrast microscopy revealed that the polyblends are heterogeneous, the rubbery ...

This work aims to probe the roles of ethylene propylene segmented copolymer (EPS) in impact polypropylene copolymers (IPCs) by rheological and morphological investigations. A series of IPCs with different EPS contents and molecular structures are prepared by an atmosphere-switching polymerization process ...
Maleic anhydride grafting ethylene-octene copolymer(POE-g-MAH) was prepared by melt grafting. 利用熔融接枝法制备了马来酸酐接枝乙烯-辛烯共聚物(POE-g-MAH),探讨了各个因素对POE-g-MAH接枝率和熔体流动速率(MFR)的影响,并得出了最佳配方、最佳工艺条件。 3. The effects of viscosity ratio on mechanical ...
