Mechanical Properties in Blends of Polypropylene and Polyolefin-Based Copolymers

Morphology and Mechanical Properties in Blends of Polypropylene and Polyolefin-Based Copolymers 

It is quite important to comprehend that the miscibility and/or compatibility in polyolefin blends dominate their material characteristics and basic properties. The lack of polarity, however, often leads to the phase-separated state in most polyolefin blends in spite of the similar chemical structure. For example, it is well known that 

We begin in Section 9.2 with the morphology in binary blends of iPP and various rubbery olefin copolymers where we remark the interrelation between the miscibility and dynamic mechanical properties. Section 9.3 describes the molecular orientation behavior under tensile deformation of iPP-based blends, and we compare the differences in deformation behavior between miscible and immiscible blends. Section 9.4 contains the solidification process in iPP-based blends where the effects of miscibility in the molten state on the crystallization of iPP matrix are discussed.
