A pre-polymer mixture for forming hydrogel particles includes a percentage of PEGDA selected to impart a target stiffness to the particles and includes, a percentage of acrylic acid selected to impart an independent target chemical function to the particles. The mixture also includes a percentage of photo-initiator to polymerize PEGDA upon exposure to a light source to impart an independently selected target size or shape or both to the particles.Type: ApplicationFiled: October 13, 2009Publication date: April 15, 2010Applicants: Massachusetts Institute of Technology, The General Hospital CorporationInventors: Ramin Haghgooie, Patrick Seamus Doyle, Mehmet Toner, Daniel Colin Pregibon

Patent number: 7696401Abstract: An absorbent material formed at least in part of a cross-linked polymer. The absorbent material has a centrifuge retention capacity as determined by a Centrifuge Retention Capacity Test of at least about 20 g/g and a gel bed permeability under load as determined by a Gel Bed Permeability Under Load Test of at least about 300×10?9 cm2 or a free swell gel bed permeability as determined by a Free Swell Gel Bed Permeability Test of at least about 2,500×10?9 cm2. The cross-linked polymer may comprise either at least about 75 weight percent anionic polymer or at least about 75 weight percent cationic polymer. In one embodiment, the cross-linked polymer is surface treated with a water soluble non-cross-linked polymer having a potential for becoming charged opposite that of the cross-linked polymer.Type: GrantFiled: July 31, 2003Date of Patent: April 13, 2010Assignee: Evonik Stockhausen, Inc.Inventors: Jian Qin, Xiaomin Zhang, Debra Ann Miller

Patent number: 7687551Abstract: Adhesive compositions useful for laminating cellulosic substrates are formulated using an aqueous emulsion of a vinyl ester polymer such as polyvinyl acetate, one or more monomers or oligomers functionalized with (meth)acrylate groups, and a photoinitiator. The adhesive is cured by drying and exposing the adhesive to UV or visible light and is particularly useful for attaching clear films to cellulosic substrates such as paper and boxboard (e.g., in the manufacture of envelopes or folding cartons having windows).Type: GrantFiled: September 6, 2006Date of Patent: March 30, 2010Assignee: Henkel CorporationInventors: Alexander P. Mgaya, Balasubramaniam Ramalingam
