The invention discloses a composition comprising one or more density modulators dispersed in a polymer matrix wherein the matrix is prepared by the metathesis of an olefin monomer using a ruthenium or osmium metal carbene catalyst. The composition may use a catalyst of the formula wherein: M is ruthenium or osmium; X and X1are either the same or different and are any anionic ligand; L and L1are either the same or different and are any neutral electron donor; R and R1are either the same or different and are each independently hydrogen or a substitutent selected from the group consisting of C1-C20alkyl, C2-C20alkenyl, C2-C20alkynyl, aryl, C1-C20carboxylate, C1-C20alkoxy, C2-C20alkenyloxy, C2-C20alkynyloxy, aryloxy, C2-C20alkoxycarbonyl, C1-C20alkylthio, C1-C20alkylsulfonyl and C1-C20alkylsulfinyl, wherein each of the substituents is substituted or unsubstituted. The density modulators are selected from the group consisting of metallic density modulators, microparticulate density modulators and macroparticulate density modulators.
