Addition Polymerization of Cyclopentadiene in the Presence of Catalytic Systems Based on Pd(0) Complexes and Organic Cocatalysts

Abstract Addition polymerization of cycloalkenes (cyclopentene, cyclopentadiene, cyclooctene, cyclooctadiene) in the presence of a new type of catalytic systems—Pd(0) complexes activated with arendiazonium salts—was studied. It was shown that cyclopentene, cyclooctene, and cyclooctadiene are not active in polymerization with these catalytic systems, while cyclopentadiene is actively involved in polymerization. The polycyclopentadiene structure was confirmed by 1H NMR spectroscopy. The molecular weight parameters and microstructure of the polymer were determined.
