Current technologies of DCP-RIM (reaction injection molding of dicyclopentadiene) are reviewed from an industrial point of view. The DCP-RIM provides high-impact, heat resistant, and insulating poly(dicyclopentadiene) thermoset resin via catalytic olefin metathesis. Control of chemical reactivities of the catalysts is one of the most important technologies for the DCP-RIM. The key properties of the catalysts are their good solubility in dicyclopentadiene and latency.
Suitable tungsten or molybdenum-based catalyst systems have been developed and used for over 30 years. These catalyst systems are comprised of inorganic tungsten (or molybdenum) salt and an air-sensitive organoaluminum as an activator. In contrast, robust Grubbs type ruthenium-alkylidene catalysts are attracted great interest in the field of the DCP-RIM. Detailed structure and reactivities of the ruthenium catalysts for the DCP-RIM are summarized.
