Polymer Networks ContainingReversibly Associating Side-GroupsMitchell Anthamatten, University of Rochester, DMR 0906627 Functional groups bearing multiple hydrogen bonding sites are under investigation to further develop shape memory polymers, self-healing interfaces, and thermoplastic elastomers. The viscoelastic properties of linear poly(hydroxy ethyl acrylate) (HEMA), a commercially important polymer, were modified by orders of magnitude by including small amount of functional ureidopyrimidinone (UPy) monomer. The kinetics and thermodynamics of water swelling were also studied. Establishing control of HEMA’s viscoelastic properties will aid in developing advanced biomaterials. water hydrophobicdomain } H-bondingdimer Poly(HEMA) complex viscosity Soft Matter, 2012 (submitted) (frequency)

They plan to attend graduate school. • Training of two PhD students who will establish careers in industrial research: the first, Dr. Jiahui Li is now employed (ConocoPhilips) as an industrial scientist. • Technical output from the current grant has jump-started a collaboration with an Industrial Research Partner in the area of shape memory polymers.
