Publication number: 20140171535Abstract: Polyol compositions containing methane linkages derived from amino acids. The polyols are obtained from the reaction of the carbonate with the cadres in the amino acids. Individual amino acids or mixtures of amino acids that are prepared from the hydrolysis of the proteins can be used.Type: ApplicationFiled: September 24, 2013Publication date: June 19, 2014Applicant: BioPlastic Polymers and Composites, LLC.Inventors: Ramani Narayan, Daniel Graiver, Elodie Hablot, Vahid Sendijarevic, Siva Rama Krishna Chalasani

Patent number: 8349032Abstract: Fuel oxygenates comprised of fatty acid or fatty acid ester derivatives which have been reacted with ozone; a base; and a lower alkanol (1 to 8 carbon atoms) are described. The oxygenates comprise ester groups at a point of cleavage by the ozone which provide oxygen in the oxygenate.Type: GrantFiled: April 16, 2008Date of Patent: January 8, 2013Assignees: Board of Trustees of Michigan State University, Bioplastic Polymers and Composites, LLCInventors: Ramani Narayan, Daniel Graiver, Kenneth W. Farminer

Patent number: 8217193Abstract: A process for the preparation of new polyols and polyesters from a natural oil or other unsaturated fatty acid esters is described. The process involves ozone cleavage of double bonds in the fatty acid chains of the oils along with coupling of a hydroxylated compound such as a mono-alcohol, a diol, or a polyol to the cleaved ends of the molecules resulting from the cleavage with a base. The resulting polyols and polyesters are as intermediates for polymers.Type: GrantFiled: September 15, 2009Date of Patent: July 10, 2012Assignees: Board of Trustees of Michigan State University, Bioplastic Polymers and Composites, LLCInventors: Ramani Narayan, Daniel Graiver, Kenneth W. Farminer, Phuong T. Tran, Tam Tran, legal representative

Patent number: 8110036Abstract: A moisture-curable, silane-modified oil is disclosed. The silane-modified oil includes an unsaturated oil having at least one unsaturated aliphatic hydrocarbon chain per molecule of the unsaturated oil, and at least one hydrolysable silyl group grafted to the unsaturated aliphatic hydrocarbon chain. The silane-modified oil has a degree of unsaturation that is substantially similar that of the unsaturated oil. A process for forming the moisture-curable, silane-modified oil according to the disclosure includes reacting the unsaturated oil with an unsaturated hydrolysable silane in the presence of a free radical initiator. Also disclosed is a cured silane-modified oil which includes the reaction product of the silane-modified oil and water. Compositions according to the disclosure have relatively low viscosities (facilitating their application to a substrate) and have relatively high levels of silane grafting (resulting in non-leaching cured compositions with a high gel content).Type: GrantFiled: October 6, 2008Date of Patent: February 7, 2012Assignees: Board of Trustees of Michigan State Univeristy, Bioplastic Polymers and Composites, LLCInventors: Ramani Narayan, Daniel Graiver, Kenneth W.
