Patent number: 9796889Abstract: The invention discloses an adhesion agent composition comprising at least one C3-C200 olefin compound having at least one metathesis active double bond, wherein the olefin is substituted or unsubstituted; and at least one compatibilizing functionality for interacting with a substrate surface. The substrate surface can be any surface, for example, silicate glasses, silicate minerals, metals, metal alloys, ceramics, natural stones, plastics, carbon, silicon, and semiconductors. The invention also discloses articles of manufacture utilizing these adhesion agents as well as methods for adhering a polyolefin to a substrate surface.Type: GrantFiled: October 29, 2015Date of Patent: October 24, 2017Assignee: MATERIA, INC.Inventors: Michael A. Giardello, Christopher M. Haar, Brian Edgecombe, Anthony R. Stephen, Li-Sheng Wang, Diana Stoianova

Patent number: 9504997Abstract: Chelating ligand precursors for the preparation of olefin methathesis catalysts are disclosed. The resulting catalysts are air stable monomeric species capable of promoting various methathesis reactions efficiently, which can be recovered from the reaction mixture and reused. Internal olefin compounds, specifically beta-substituted styrenes, are used as ligand precursors. Compared to terminal olefin compounds such as unsubstituted styrenes, the beta-substituted styrenes are easier and less costly to prepare, and more stable since they are less prone to spontaneous polymerization. Methods of preparing chelating-carbene methathesis catalysts without the use of CuCl are disclosed. This eliminates the need for CuCl by replacing it with organic acids, mineral acids, mild oxidants or even water, resulting in high yields of Hoveyda-type methathesis catalysts.Type: GrantFiled: May 8, 2014Date of Patent: November 29, 2016Assignee: MATERIA, INC.Inventors: Richard L. Pederson, Jason K. Woertink, Christopher M. Haar, David E. Gindelberger, Yann Schrodi
