Layered double hydroxides for tailored molecular weight distributed polyolefins

Image from Licence Details: Layered double hydroxides for tailored molecular weight distributed polyolefins

Applications: Catalysts, Catalyst Supports, Polymerisation, Olefins, Polyethylene

Oxford scientists have developed a novel technique to control the Molecular Weight Distribution (MWD) of polymer chains formed during the polymerisation of olefins. This method uses one single-site catalyst supported Layered Double Hydroxide (LDH).

Features Benefits
  • Synthesis of novel mixed metal Layered Double Hydroxides (LDHs) metallocene support compositions.
  • Suitable of supporting an olefin polymerisation catalyst.
  • Alternative to classical polyethylene catalysts such as Ziegler-Natta and Phillips systems.
  • Tailored polymerisation of olefins (especially bimodal polyethylene).
  • Capable of affording a multimodal polyolefin.
  • Catalyst support can tune the Molecular Weight Distribution (MDW) of a polyolefin.
  • Uses single olefin polymerisation catalyst.
  • Improved production methods and energy saving.
  • Directly produce a polymer with two distinct MWDs in single reactor.
  • Alternative to melt-blending of polymers.
  • Avoids high viscosity mixing problems with (ultra)high molecular weight polyethylene.
  • Alternative to complex reactor setup and catalyst design.
