Abstract:
A method for making a high temperature coating comprising:exposing a surface coated with precursor polymer to conditions effective to cure said precursor polymer and to decompose said precursor polymer to a metal carbide comprising about 3 wt. % impurities or less, wherein said precursor polymer is made by a process comprising mixing a salt of a transition metal comprising a first metal with an organometallic compound comprising a second metal which is displaceable by said transition metal, said second metal being bonded to at least one polymerizable organic component selected from the group consisting of allyl groups, vinyl groups, and olefinic groups comprising from about 2 to about 8 carbon atoms under conditions effective to form organo-transition metal complexes; and, subjecting said organo-transition metal complexes to conditions effective to polymerize said organo-transition metal complexes, forming said precursor polymer.
