POLYOLEFINS: Controlling Polyolefin Properties by In-Reactor Blending: 2. Particle Design

Martin Ruff*, Christian Paulik

Structure properties of in-reactor-blended ultra-high molecular weight polyethylene (UHMW-PE) reactor powders are presented, and it is shown that the particle morphology can be designed by precisely controlled multi-stage (slurry) polymerization. A novel kind of surface structure, named cocoon-structure, of bimodal PE reactor powders from multi-stage polymerizations is presented.
