Patent number: 10126298Abstract: Open three-dimensional network, microporous hydrogels containing substrates attached to binding molecules is disclosed. The hydrogel is comprised of a hydrated gel matrix containing substrates embedded in the matrix. The substrates are attached to binding molecules that selectively bind specific molecules that encounter the hydrogel. Thus the hydrogel serves to selectively bind out target molecules from an aqueous environment or sample that the hydrogel comes in contact with and concentrates them within the hydrogel.Type: GrantFiled: May 4, 2015Date of Patent: November 13, 2018Inventor: Arman Nabatian

Patent number: 9884968Abstract: The present invention relates to new acrylic associative thickening agents which, when polymerized in the presence of particular polyglycerols, ultimately result in an increase of the open time of the paint or of the thick coating in which they are incorporated. By so doing, painters and applicators will have more time to work the paint layers gradually or to correct imperfections such as paint droplets, traces of brushes and filling-knives.Type: GrantFiled: October 4, 2012Date of Patent: February 6, 2018Assignee: COATEXInventors: Denis Ruhlmann, Jean-Marc Suau
