Extended time sweeps at 20 C were conducted at 1 %, 10%, and 300% with intermitted frequency sweeps to monitor the effect of oscillation amplitude on the ROMP rate. In the linear regime, oscillation amplitude seems to have little effect on the ROMP rate. In the nonlinear regime (above 10% strain), ROMP is significantly delayed as indicated by the extended mutation time.

Repeated frequency sweeps undergoing ROMP at 20C with intermittent time sweeps were conducted on ROMPing resin to show the effect of oscillation frequency on the reaction rate of ROMP. The frequency sweeps reveal a critical gel state (power law dependence of moduli) occurring at different times depending on oscillation frequency

linear viscoelastic measurements of DCPD that has been ROMPed to above the printability state and then quenched with the addition of EVE which binds to the catalyst. These tests reveal minimal mutation over the duration of the test after adding 500 eq of EVE to GC2 by molecular weight. However, tests later revealed that ROMP continued happening over the order of weeks meaning that the 500 eq of EVE was not sufficient to completely stop ROMP.

Frequency sweep tests reveal a power law behavior in the low frequency (terminal) regime. Creep tests reveal minimal mutation between tests

Conducted repeated frequency sweeps on ROMPing DCPD to observe the mutation of monomer at 20 C. Power law dependence of moduli on frequency is evident

Andrew Lum ran fixed frequency tests on a 10k:1:1 DCPD:GC2:TBP resin at 20 C on the DHR-3 at the Beckman Institute at UIUC. These were used to probe the frequency dependence of the crossover point in moduli to determine the printability window.
