Title: Innovations by Inventor Johannes J. Snel
Introduction
Johannes J. Snel, an inventor hailing from Amsterdam, Netherlands, holds an impressive portfolio of 16 patents. His work primarily focuses on innovations in polymerization processes, contributing significantly to the field of materials science.
Latest Patents
One of Snel's latest patents introduces an enhanced polymerization catalyst that aims to improve the production of linear alternating polymers made from carbon monoxide and ethylenically unsaturated hydrocarbons, particularly propylene. This innovative process incorporates an aromatic amine within the catalyst composition, which includes a palladium salt, the anion of a strong non-hydrohalogenic acid, and a bidentate ligand of phosphorus. Significantly, the inclusion of the aromatic amine reduces the presence of 3-alkyl-2,5-furandiyl moieties in the polymer chain, paving the way for higher-quality materials.
Another noteworthy patent details a catalyst composition useful in preparing polymer compositions. This invention features a Group VIII metal and a phosphorus bidentate ligand, defined by the formula (R.sub.2)(R.sub.4)P--R.sub.3 --P(R.sub.2)(R.sub.4). Here, R.sub.2 and R.sub.4 represent optionally polar substituted alkyl groups with differing carbon numbers, while R.sub.3 serves as a divalent organic bridging group consisting of four atoms. These catalyst compositions are particularly effective for creating copolymers of carbon monoxide and .alpha.-olefins containing at least three carbon atoms.
