  1. "Part A. Functional Modular Phenylacetylene Units: A ""Molecular Turnstile."" Part B. Progress Towards an Electrochemically Active 9-Phenylcarbazole Hyperbranched Polymer"

    Bedard, Thomas CraigUniversity of Illinois at Urbana-Champaign2015

    Part B. Progress towards a new family of hyperbranched polymers based on the condensation of an AB$\sb2$ 9-phenylcarbazole monomer 169 has been described. Initial condensation reactions have provided material of greater than 100,000 mw as determined by GPC. No estimate of the degree of branching …

  2. Self-Condensing Ring-Opening Metathesis Polymerization

    Almuzaini, Hanan NasserVirginia Tech2023

    Ring-opening metathesis polymerization (ROMP) is a great tool for synthesizing polyolefin materials with different topologies, including hyperbranched polymers—polymers with high degrees of branching and many end groups. However, hyperbranched polymer synthesis via ROMP is challenging due to …

  4. Synthesis and Characterization of Multiphase, Highly Branched Polymers

    Fornof, Ann R.Virginia Tech2006

    … is frequently cited as a key application for hyperbranched polymers. However, the high degree of branching in these polymers restricts entanglement and the resultant mechanical properties suffer. Longer distances between branch points may allow entanglements. Highly branched polymers, where …

  7. Synthesis and characterization of novel conjugated polymers and rod-coil block copolymers

    LU SU2004

    A series of polyfluorene-based (PF) conjugated copolymers have been synthesized to improve the spectral stability, hole-injection properties and water processibility which are the major challenges for PF-type materials. The focus of this work has been to examine whether properties of conjugated …

    Ozer, Imran2021

    … needs, we have developed a “next-gen” PEG-like polymer, poly[oligo(ethylene glycol) methyl ether methacrylate] (POEGMA). POEGMA is an amphiphilic, hyperbranched polymer that breaks up the long ethylene glycol sequences in PEG and presents them as much shorter oligomeric ethylene glycol (OEG) …
