Pushing the Boundaries with Proxima Thermoset Norbornene Polymer Technology



New polymeric materials have played an important role in accessing previously challenging oilfield environments. Polydicyclopentadiene (pDCPD) is the prototypical example of a thermoset polymer made by ring-opening metathesis polymerization (ROMP), and is characterized by high toughness, low water absorption, and excellent resistance to corrosive fluids. Despite a promising price/performance profile, applications of pDCPD have been limited in part by the sensitivity of the curative catalysts which restricted their use to unreinforced systems processed by reactive injection molding (RIM).

Recent advances in catalyst technology have led to a series of curatives that are more robust and dramatically broadened the applicability of pDCPD beyond what was previously possible. The new catalysts are compatible with:

• Composite fillers, including fibers (glass and carbon) and particles (glass bubbles and mineral fillers)

• Alternative processing techniques, including casting, infusion (RTM, VARTM), rotomolding, and pultrusion

• Property modulators, to provide enhanced elongation, Tg, toughness, and chemical resistance

This paper will outline recent advances in ring-opening metathesis polymer development, with a particular emphasis on high temperature materials (up to 450 °F) and composites for downhole applications.
