  • Effects Of Process Method And Quiescent Coarsening

    We compare how solid-state shear pulverization sssp, batch melt mixing bmm, and static melt-state annealing affect the morphology of an immiscible blend of polypropylene pp and ethylene--olefin copolymer eoc.For 8515 wt ppeoc blends, sssp and bmm led to log-normal distributions of dispersed-phase particle size.
