Abstract
Thermosetting resin pipes and pipe fittings are provided which are prepared by polymerizing a cyclic olefin monomer in the presence of a ruthenium or osmium metathesis polymerization catalyst. These articles may be prepared by various methods, such as centrifugal casting. Reinforced articles may also be prepared by filament winding.
