Abstract
A reinforced polymeric matrix comprising a glass mat and a norbornene polymer surrounding the glass mat, the glass mat is composed of at least one glass fiber treated with a silane coupling agent and a binder adhering the glass fiber(s) to the norbornene polymer; the binder is selected from polyolefins, vinyl aromatic polymers, and ring-opened polymers of at least one norbornene-type monomer containing at least one norbornene group. Process for making a reinforced polymeric matrix comprises positioning a glass mat within a mold, the glass mat having been treated with a hydrocarbon polymer binder; mixing a plurality of streams, one stream containing a catalyst of a metathesis catalyst system, another stream containing a cocatalyst of a metathesis system, and at least one of the streams containing at least one norbornene-type monomer which is liquid at room temperature to form a mixed stream; introducing the mixed stream into the mold around the mat; polymerizing by ring opening the monomer(s) in the mold; and extracting from the mold the reinforced polymeric matrix, wherein the norbornene polymer is thermoset.
