摘要: The morphology evolution under shear during different processing is indeed an important issue regarding the phase control as well final physical properties of immiscible polymer blends. High-speed thin wall injection molding (HSTWIM) has recently been demonstrated effective method to prepare alternating multilayered structure. To understand formation mechanism better and explore possible for blends HSTWIM, relationship between based on polypropylene (PP) HSTWIM some intrinsic blends, including viscosity ratio, interfacial tension, melt elasticity, systematically investigated in this study. Blends PP containing polyethylene (PE), ethylene vinyl alcohol copolymer (EVOH), polylactic acid (PLA) are used examples. Compatibilizer also added into respective alter their interaction. It that dispersed can ...
