To "J. Arthur God" You've never done olefin metathesis on hindered substrates. Grubb's cataylsts are commercially available but Schrock's - especially adept at working hindered and unstrained substrates - are not.

You do not do organic synthesis or you would know the Wittig reaction is intolerant of hindered carbonyls. Benzil systems will not do well in alkaline reducing conditions.

"Collaboration" Academic groups particularly skilled in executing the polymerization and studying the results do not contain the skills to obtain required monomers.

Naval shells are interesting when they land, but they lack a cute little button on their buttoms to send them on their way.
