Poly-glycine I+II - Help!

[joku at nmr.lpc.ethz.chJoergKuemmerlen]

Hello.

I am wondering if anybody has a recipe for the state of the art
synthesis of poly-glycine (form I and II). The only instruction
I have found so far is very old and I am looking for a more advanced
strategy for the synthesis of these two forms of poly-glycine.

Furthermore : How can poly-(Gly-Ala) be synthesized ???

Thanks in advance
Joerg
