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 mineralfillers)
•Alternative processing techniques, including casting, infusion (RTM, VARTM), rotomolding, andpultrusion
•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.
Daryl Allen is the Director of Applications Development at Materia Inc., where for almost 11 years he has focused on the development and commercialization of thermoset polymer and catalyst products. He obtained a Bachelor of Science degree in chemistry and a Ph.D. in organometallic chemistry with a focus on catalysis from the University of New Brunswick in Canada. After graduate school, he had the opportunity to work with Nobel Laureate Prof. Bob Grubbs at the California Institute of Technology as a Natural Sciences and Engineering Research Council of Canada postdoctoral fellow. Outside of work, Daryl is an avid sports fan, enjoys playing a round of golf whenever possible and loves being dad to a young son and daughter back in Pasadena, CA.
