Abstract
ABSTRACTPolyolefin elastomer (POE)/poly(trimethylene terephthalate) (PTT) microfibrillar composites (MFCs) were successfully fabricated by multistage stretching extrusion with an assembly of laminating‐multiplying elements (LMEs). The morphologies of these novel materials were greatly influenced by the compositions. The number of microfibrils increased with increasing PTT concentration, as revealed by scanning electron microscopy. The tensile strength was the highest along the extrusion direction at the weight ratio of 85/15. Moreover, dynamic rheological results showed that the storage modulus, loss modulus, and complex viscosity were the highest while the tan δ was the lowest for MFCs prepared at the weight ratio 85/15 compared with the neat POE, especially at low frequency (ω < 1 rad/s). In addition, the PTT microfibrils had more effect on the rheological properties compared to the PTT particles. However, the differences became negligible at high frequency (ω > 100 rad/s). © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43797.
