The biomaterials are formed from a composition comprising at least a first and a second precursor molecule, wherein: i) the first precursor molecule is a poly(ethylene glycol) based polymer having x nucleophilic groups selected from the group consisting of thiol or amino groups, wherein x is greater than or equal to 2 ii) the second precursor molecule is of the general formula: A-[(C3H6O)n—(C2H4O)m—B]i wherein m and n are integers from 1 to 200 i is greater than 2 A is a branch point B is a conjugated unsaturated group The precursors are selected based on the desired properties of the biomaterial. Optionally, the biomaterials contain additives, such as thixotropic agents, radiopaque agents, or bioactive agents.Type: ApplicationFiled: April 14, 2008Publication date: October 16, 2008Inventors: Annemie Rehor, Simona Cerritelli

Publication number: 20080226584Abstract: The present invention relates to a substrate having one or more antimicrobial or antistatic properties. Such properties are imparted by applying a coating or film formed from a cationically-charged polymer composition. The polymer composition includes a noncationic ethylenically unsaturated monomer and an ethylenically unsaturated monomer capable of providing a cationic charge to the polymer composition. Optionally, the polymer composition includes a steric stabilization component incorporated into the cationically-charged polymer composition. The present invention also relates to a personal care product and polymeric material comprising a base polymer blended with the above cationically-charged polymer composition.Type: ApplicationFiled: May 6, 2008Publication date: September 18, 2008Inventor: Venkataram Krishnan

Patent number: 7388050Abstract: A hyperbranch polymer is bonded to a pore surface existing on a SiO2 glass porous body, such that the hyperbranch polymer is bonded to the pore surface only at the base end moiety. The hyperbranch polymer has a first generation branched moiety branched from the base end moiety, a second generation branched moiety further branched from the first generation branched moiety, and a third generation branched moiety further branched from the second generation branched moiety. A functional group, such as sulfonic acid group, from which a proton is capable of being dissociated, is bonded by substitution to the terminal end of the third generation branched moiety.Type: GrantFiled: December 23, 2004Date of Patent: June 17, 2008Assignee: Honda Motor Co., Ltd.Inventors: Hitoshi Iwadate, Yuji Isogai
