Abstract
Aluminum-nitrogen polymers comprising a backbone of alternating aluminum and nitrogen atoms both having pendant organic groups, wherein some of the pendant organic groups are unsaturated, are prepared by reacting an unsaturated organic nitrile with a dialkylaluminum hydride. The polymers are crosslinked by supplying energy to generate free radicals. The crosslinked polymers can be pyrolyzed to form an aluminum nitride ceramic.
