The polymerization of -y-benzyl+glutamate NCA initiated by n-hexylamine in DMF proceeds with two successive propagation r a h whose ratio is about 1.5.

## 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
