| 1. A metallized thermoset comprising:
a crosslinked metallized polymer comprising a backbone comprising:
an acetylenic repeat unit, at least one of the acetylenic repeat units comprising a (MLx)y-acetylene complex;
wherein each M is an independently selected metal;
wherein each L is an independently selected ligand; and
wherein x and y are positive integers; and
one or more repeat units selected from —SiR2—(O—SiR2)n— and —SiR2—(O—SiR2)n-[Cb-SiR2—(O—SiR2)n]m—;
wherein each R is an independently selected organic group;
wherein each Cb is an independently selected carborane; and
wherein each n is an independently selected integer greater than or equal to one; and
wherein each m is an independently selected integer greater than or equal to zero;
wherein the metallized thermoset comprises one or more of a crosslink between acetylene groups and a polycarbosiloxane crosslink.
