Latest Patents

Stephanie holds a patent for a "Staged reactor process." This process involves the in situ blending of polymers by contacting ethylene and one or more comonomers in two or more fluidized bed reactors. The catalyst system used in this process includes a magnesium/titanium-based precursor containing an electron donor and a hydrocarbyl aluminum cocatalyst. The improvement in this process allows for the adjustment of the melt flow ratio and molecular weight of the blend by manipulating the mole ratio of a precursor activator compound to the electron donor. This innovation is crucial for enhancing the properties of polymer blends.
