Abstract
Compositions including fibers, fillers, reinforcing agents or other property-enhancing agents added to a polymeric matrix formed from DCPD monomer or related compounds such as norbornene and norbornadiene are disclosed. The composition has a mechanically forgiving matrix due to the polymer with the inherent strength and other physical properties of the enhancement agent according to the invention. Enhancement agents according to the invention generally include inorganic, organic and metallic substances in a variety of forms.

A composition of matter, comprising:
- (a) a ruthenium or osmium carbene complex catalyst having a ruthenium or osmium metal center that is in a +2 oxidation state an electron count of 16, and is pentacoordinated;
- (b) a functionalized or unfunctionalized olefin capable of polymerization by said catalyst;
- (c) an electron donor or Lewis base in a concentration sufficient to change the rate of an olefin metathesis catalyzed by said carbene complex catalyst in the absence of said electron donor or Lewis base;
- and
- (d) an additive for enhancing at least one bulk property of said composition of matter without interfering with the polymerization of said olefin by said catalyst.
