TL;DR: In this article, a reinforced polymeric matrix comprising a glass mat and a norbornene polymer surrounding the glass mat is constructed, which is composed of at least one glass fiber treated with a silane coupling agent and a binder adhering the glass fiber(s) to the norbornenes polymer.
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.

TL;DR: In this paper, an efficient palladium-catalyzed cycloaddition between ynamides and norbornenes or norbornadienes was reported, and a chiral phosphapalladacycle was tested to carry out this transformation in an enantioselective fashion.
Abstract: An efficient palladium-catalyzed [2 + 1]cycloaddition between ynamides and norbornenes or norbornadienes is reported. Both phosphapalla- dacycles and palladium/secondary phosphine oxide catalytic systems were found to be competent for the transformation allowing the preparation of ami- nomethylenecyclopropanes. The reaction showed general applicability to various functionalized bicyclo[2.2.1]hept-2-enes and ynamides. A chiral phosphapalladacycle was tested to carry out this transformation in an enantioselective fashion.
