I gather that you have been out of town and busy since I phoned you, and so I am sending you this reminder.
I would like an opportunity to tell you what I have done on making a reproducible polymer, why I think it has been unsuccessful, and what approaches are now apparent to me.  I would like your opinion on whether these approaches are promising, and, if so, who might be willing to support them.
