In situ formation of polypropylene (PP) fibrils in the olefinic block copolymer (OBC): effect of viscosity ratio and OBC block architecture

摘要

Microfibrillar composites (MFCs) can be created when the viscosity ratio of polypropylene (PP) and olefinic block copolymer (OBC) is well controlled. PP can be easily deformed into well-refined microfibrils in OBC with different architectures. The mechanical properties of the obtained MFCs are prominently improved.
