ABSTRACT:
A reaction solution comprising a mixture of tricyclopentadiene, a norbornene monomer with at least 3 rings in its backbone, a 5-alkenyl-2-norbornene pot life adjusting agent along with a molybdenum type catalyst system gives prolonged pot life without extending time to exotherm (e.g., smoking time). By utilizing this reaction solution it is possible to bulk polymerize reinforced or unreinforced articles in a mold via ring-opening polymerization. Articles so obtained have good outward appearance and excellent physical properties.
