Earlier published rheological data of methyl methacrylate (MMA) heated and isothermally polymerized at temperatures between 50 and 80 C have been reanalyzed using three semiempirical models of viscosity advancement including a modified Boltzmann sigmoidal model, a microgel model for cure, and a first-order isothermal kinetic model. These alternative models possessed few fitting parameters and could be used without requiring more experiments to be run. For each dataset as a function of temperature, the analysis resolved time constants associated with both the induction time for polymerization and the rate of viscosity rise, which were inversely related to the polymerization temperature. We found the sigmoidal model the most robust to accommodate nonlinearities in viscosity advancement with radical polymerization of MMA.

“…RF has a functionality of 3, and thus immediately forms a threedimensional cross-linked network, whereas DCPD has a functionality of two thus forming predominately linear chains (the reactivity of the second double bond in DCPD is lower due to its lower ring strain 20 ). To force the DCPD system into a 3D cross-linked network morphology, and thus to increase both viscosity and strength at the sol-gel transition, we tested the addition of appropriate cross-linkers.…”

“…We have identified a polymeric material, dicyclopentadiene (DCPD) nano molecular resin [6,7] to strengthen the pothole repair materials [8,9]. We take the approaches of utilizing the low viscosity characteristic of the DCPD resin, which is controllable from similar to water to very viscose, to infiltrate the asphalt-aggregate mixtures.…”

We have applied dicyclopentadiene (DCPD) resin for reinforcing pothole patch materials due to its unique propertieslow cost, low viscosity at beginning and ultra-toughness after curing, chemical compatibility with tar, tunable curing profile through catalyst design. In this paper, we have designed a two layer structure -well compacted base layer and DCPD reinforced 1-1.5" top layer -for pothole repair. By choosing two graded asphalt mixes, a porous top layer and fully compacted base layer was prepared after compaction and ready for DCPD resin infiltration. The DCPD curing and infiltration profile within this porous top layer was measured with thermocouples. The rutting resistance was tested with home-made wheel rutter. The cage effect due to the p-DCPD wrapping was characterized with wheel penetration test. The results showed that this two layer structure pothole repair has greatly improved properties and can be used for pothole repair to increase the service life.
