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...

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 ...

The direct current potential drop (DCPD) technique may be used in crack propagation tests to measure the growth rate (CGR). Potential probes attached specimen allow variation of length estimated. In this research, DCPD using one single probe was applied solid bar specimens (i.e., without any initial notch or crack) subjected low-cycle fatigue testing a simulated pressurized water reactor (PWR) ...
