Round 1

Reviewer 1 Report

The manuscript titled “Structural and Mechanical Properties of Ionic Di-block Copolymers via a Molecular Dynamics Approach” used coarse grained molecular dynamics simulations to investigate the structural and mechanical behaviors of ionic homopolymers  and di-Block copolymers. Overall, the manuscript is well designed and executed. Please review the manuscript for grammatical errors.

Reviewer 2 Report

Comments and questions:

The  section 2 and 3 and should be rewritten. It should be well orginazed. How is the temperature rate determined in Figure 4. How is the stress calculated? No overshoot is seen in Figure 5. why?

Round 2

Reviewer 2 Report

1. please add a formula or reference of the reduced charge calculation.
2. why is the cut-off set as 1.68?
3. Is the soft-core potential applied on each pair of CG beads or the CG beads on

different chains?
4. Why the pressure is 4.5?
5. please check formula 2.Is it the same as the original KG model?
