Latest Patents
Paivi L Pitkanen holds a patent for a "Stereospecific catalyst system for polymerization of olefins." This invention allows for the polymerization of olefins, especially propene and ethene, using a Ziegler-Natta catalyst system. The system includes a transition-metal-based procatalyst and an organometallic cocatalyst, along with an external donor that controls the stereospecificity of the produced polymer. The use of an acetal derivative of an aldehyde with two ether groups, such as dimethoxyphenylpropane, achieves good stereospecificity while maintaining high hydrogen sensitivity. This innovation provides an effective method for controlling the molecular weight of the polymer by adjusting the hydrogen levels during the reaction.
