Cure Kinetics of the Ring-Opening Metathesis Polymerization of Dicyclopentadiene
The cure kinetics of polydicyclopentadiene prepared by ring-opening metathesis polymerization with three different concentrations of Grubbs’ catalyst were examined with differential scanning calorimetry. The experimental data were used to test several different phenomenological kinetic models. The data were best modeled with a model-free isoconversional method. This analysis revealed that the a...
متن کاملCure Kinetics of Ring-Opening Metathesis Polymerization of Dicyclopentadiene
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...
متن کاملSelf-Organized and Cu-Coordinated Surface Linear Polymerization
We demonstrate a controllable surface-coordinated linear polymerization of long-chain poly(phenylacetylenyl)s that are self-organized into a "circuit-board" pattern on a Cu(100) surface. Scanning tunneling microscopy/spectroscopy (STM/S) corroborated by ab initio calculations, reveals the atomistic details of the molecular structure, and provides a clear signature of electronic and vibrational ...
متن کاملROMP Reactivity of endo- and exo-Dicyclopentadiene
The activation parameters for the ring-opening metathesis polymerization (ROMP) of endo(1) and exo-dicyclopentadiene (2), endo-1,2-dihydrodicylopentadiene (3), and norbornene (4) in the presence of Grubbs’ catalyst were determined using in situ NMR. The exo isomer of DCP was found to be more than an order of magnitude more reactive than the endo isomer. endo-DCP was found to have reactivity sim...
متن کاملThermal properties of ruthenium alkylidene-polymerized dicyclopentadiene
Differential scanning calorimetry (DSC) analysis of ring opening methatesis polymerization (ROMP) derived polydicyclopentadiene (PDCPD) revealed an unexpected thermal behavior. A recurring exothermic signal can be observed in the DSC analysis after an elapsed time period. This exothermic signal was found to be proportional to the resting period and was accompanied by a constant increase in the ...
