Patent number: 7671162Abstract: Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer.Type: GrantFiled: August 26, 2005Date of Patent: March 2, 2010Assignee: DSM IP Assets B.V.Inventors: Robert S.

Publication number: 20090253842Abstract: Thermoplastic polyurethanes having an alternating sequence of hard and soft segments in which a nanostructured polyhedral oligosilsesquioxane diol is used as a chain extender to form a crystalline hard segment constituting SMPs. The polyurethanes are formed by reacting a polyol, a chain extender dihydroxyl-terminated polyhedral oligosilsesquioxane and a diisocyanate. The polyurethanes have multiple applications including for example, implants for human health care, drug delivery matrices, superabsorbant hydrogels, coatings, adhesives, temperature and moisture sensors, etc.Type: ApplicationFiled: March 13, 2009Publication date: October 8, 2009Inventors: Patrick T.
