Poly(ethylene terephthalate) and polypropylene (PET/PP) were compounded and pelletized with a single-screw extruder. Standard ASTM tensile test specimens were made by injection moulding. The blends are stronger and sti †er than the plain PP specimens. The addition of a compatibilizer, EPOLENE E-43,

Rheological and morphological studies were performed on polymer blends of ethylene-octene copolymer [polyethylene elastomer (PEE)] and polypropylene (PP). The viscosities of PEE, PP, and PEE/PP blends were analyzed using an Instron capillary rheometer and a Rheometrics Dynamic Stress Rheometer, SR 2
The dynamic viscoelastic properties of polypropylene (PP)-maleated PP blends in the molten state have been investigated with a dynamic mechanical thermal analyzer (PL-DMTA MKII) at a frequency range () of 0.6 ء 10 Ϫ1 -3.14 ء 10 2 rad s Ϫ1 . In the study, the blends were prepared by melt-blending
