Quantitative Characterization of Dispersed Particle Size, Size Distribution, and Matrix Ligament Thickness in Polypropylene blended with Metallocene Ethylene-Octene Copolymers

摘要

The average rubber particle size, size distribution, and matrix ligament thickness between particles in polypropylene blends containing metallocene catalyzed ethylene-octene copolymers have been quantitatively analyzed, as functions of blend composition and phase viscosity ratio.
