Patent number: 10519100Abstract: According to one aspect, a process of forming a diisocyanate compound from limonene is disclosed. The process includes performing an oxidation reaction to form a limonene-ketone from limonene having a ketone group at a first position. The process includes performing a conjugate addition reaction on the limonene-ketone to form a limonene-nitrile having a nitrile group bonded at a second position. The process also includes performing a reductive amination reaction on the limonene-nitrile to form a limonene-diamine by reducing the nitrile group to form a first amine group and converting the ketone group to a second amine group. The process further includes forming the diisocyanate compound by converting the first amine group of the limonene-diamine to a first isocyanate group and the second amine group of the limonene-diamine to a second isocyanate group.Type: GrantFiled: July 13, 2018Date of Patent: December 31, 2019Assignee: International Business Machines CorporationInventors: Brandon M. Kobilka, Jason T. Wertz, Joseph Kuczynski, Scott B. King

Publication number: 20100234482Abstract: The present invention relates to a method for producing an isocyanate-based polymeric material by polymerizing a reaction mixture which comprises different reaction components, including at least one polyisocyanate component and at least one component which is reactive towards said polyisocyanate component. The reaction components comprise at least one anchor component which has at least one anchor group which enables to bond a functional component covalently to the polymeric material. The anchor group is a reactive unsaturated group which does not react during the polymerisation process so that the polymerisation process is not interfered. The anchor group is selected to that it can bind the functional component by a click chemistry reaction to the polymeric material.Type: ApplicationFiled: June 26, 2008Publication date: September 16, 2010Applicant: Universiteit GentInventors: Filip Du Prez, David Fournier, Peter Spanhove
