Polymers of norbornenyl-modified peptide-based enzyme substrates have been prepared via ring-opening metathesis polymerization (ROMP). Peptides displayed on water-soluble homopolymers retain the ability to be enzymatically processed by a disease-associated enzyme. In contrast, when the peptides are densely arrayed on a nanoparticle derived from a self-assembled amphiphilic block-copolymer, they...

Norbornenyl cyclic elastin-like peptides were polymerized via ring opening metathesis polymerization (ROMP) to generate thermally responsive brush polymers. The thermally-responsive nature of the materials could be attenuated by the addition of a proteolytic enzyme that causes the cyclic peptide side chains to be linearized.

A series of alkene bearing small molecules were electrografted to the surface carbon fibers using in situ generation aryldiazonium salts. These used as an anchoring point for use Ring Opening Metathesis Polymerization (ROMP) a ‘graft from’ approach fiber modification. After modification, evaluation these modified epoxy resin, single fragmentation test, showed significant increases interfacial s...

Through a modular ROMP (ring-opening metathesis polymerization) strategy, a random copolymer with anti-thrombotic activity and imaging capability has been constructed from RGD, rhodamine B and PEG modified norbornene monomers. As we expected, these tri-component polynorbornenes exhibit significant enhancement in anti-thrombotic efficacy and bioavailability in vivo.

An efficient strategy for the synthesis of monoamine end-functionalized living polymers using ringopening metathesis polymerization with ruthenium initiators is reported. A new end-capping agent for this purpose was synthesized, and its efficiency for end-functionalization was evaluated using two common ruthenium-based initiators. Finally, terminal cross-metathesis was also explored as another ...

The cure kinetics of polydicyclopentadiene (pDCPD) prepared by ringopening metathesis polymerization with three different concentrations of Grubbs’ catalyst was examined using differential scanning calorimetry (DSC). The experimental data were used to test several different phenomenological kinetic models. The data are best modeled with a “model-free” isoconversional method. This analysis revea...
