Latest Patents

Deok Kyeong Kim holds a patent for a "High stereospecific polybutylene polymer and highly active process for preparation thereof." This patent discloses a process for preparing a high stereospecific (isotactic) polybutylene polymer by polymerizing a reactive monomer, 1-butene, in the presence of a catalyst and inert gas. The process allows for the production of a high stereospecific polybutylene polymer with much higher activity than previously known methods. The resulting polymer is characterized by a homopolymer of 1-butene or a copolymer containing α-olefin with up to 40% by weight of a comonomer. Notably, titanium in the catalyst residues is not detected at the ppm level, and the stereospecificity (Isotactic Index, mmmm %) determined by C-NMR is 96 or more, with a molecular weight distribution (Mw/Mn) of 3-6, which can be controlled to 8 or more.
