ABSTRACT:
A metallized thermoset containing a crosslinked metallized polymer having a backbone having an acetylenic repeat unit and —SiR2—(O—SiR2)n— and/or —SiR2—(O—SiR2)n-[Cb-SiR2—(O—SiR2)n]m—. At least one of the acetylenic repeat units contains a (MLx)y-acetylene complex. The metallized thermoset contains a crosslink between acetylene groups and/or a polycarbosiloxane crosslink. M is a metal, L is a ligand, x and y are positive integers, R is an organic group, Cb is a carborane, and n and m are greater than or equal to zero. A method of making a metallized thermoset by providing a metallized polymer and heating the metallized polymer. The metallized polymer contains the above backbone. Heating the metallized polymer forms crosslinks between acetylene groups and/or polycarbosiloxane crosslinks.
