Abstract
A method is disclosed for preparing filled shaped articles of metathesis polymerized poly(cycloolefins) wherein an inorganic filler material is treated with a norbornene-substituted silane coupling agent. The norbornene moiety copolymerizes with the metathesis polymerizable monomer and the silane moiety creates a bond with the filler. Products are characterized by improved physical properties.
