Usefulness: Polyolefin catalyst component using non-covalent interactions | Polyolefin catalyst component using non-covalent interaction with the injection molding
Summary: The catalyst is for use in polymerizing olefin e.g. ethylene, propylene, 1-butene, 2-pentene, 1-hexene, 1-octene, styrene, 1,3-butadiene, norbornene, each being optionally substituted. It is used in olefin polymerization processes e.g. gas, high-pressure liquid, slurry, bulk solution, and/or suspension-phase techniques.
Novelty: New polyolefin catalyst for use in polymerizing olefin e.g. ethylene, propylene, 1-butene, 2-pentene, 1-hexene, 1-octene, styrene, or 1,3-butadiene,

*Abstract

Non-confidential Abstract of Invention: A method of manufacture is disclosed for the production of surfaces which are chiral (i.e., having hardness). These chiral surfaces are produced on achiral substrates by electrodeposition. The handedness of the films is determined by the chirality of solution precursors. The chiral surfaces can be used as heterogeneous catalyst for the enantiospecific synthesis of chiral molecules. They can also be used to produce enantiospecific chemical and biological sensors. The main application of the invention is envisioned to be the production and analysis of single enantiomer drugs in the pharmaceutical industry. There are presently no commercial heterogeneous catalysts used for chiral synthesis. It may also be used to produce sensors for chiral chemical warfare agents. The method is simple and inexpensive, and is widely applicable.
