The polymerization was studied in detail using ),-benzyl N-carboxy-L-glutamate anhydride (BGA). Compounds such as tributyltin methoxide, bis(tributyltin)oxide, and N-tributyltin imidazole polymerized BGA while others like dibutyltin dichloride, which are Lewis acids, failed. Polymerization of BGA in

## Abstract Various kinds of NCA's were polymerized in dimethyl sulfoxide (DMSO). DL‐Alanine NCA polymerized at a fast rate without initiator, the rate being represented by __R__~__p__1~ = __k__[M]^1/2^. When the polymerization was carried out in chloroform in the presence of DMSO, the rate was rep
