What is it about?
A theoretical study on ROPs of alanine and sarcosine NCAs. Primary (RNH2) and secondary amines (R2NH) initiate their polymerization in a similar way and show the same rate.

Why is it important?
An detailed mechanism explanation of living block copolymerizations of NCAs in both way: Ala_NCA then Sar_NCA and also Sar_NCA then Ala_NCA.
Perspectives
If so, why can't Ala_NCA and Sar_NCA carry out random copolymerization? ;-p
