Round 1
Reviewer 1 Report
This review paper discusses melt-spun PAN fibers as precursor of carbon fibers. The author summarized chemical and physical approaches to reduce melting point of PAN-based copolymers to make them processable, and discussed how to address thermal oxidative stabilization. This article is well organized. The only issue is the numbering of conclusion should be 5 instead of 6.

Dear reviewer,
Thank you for your recommendation.
Reviewer 3 Report
The review work titled “Melt-spinnable Polyacrylonitrile – an Alternative Carbon Fiber Precursor”, is really interesting, but there are some needs to be added before accepting this review work.
1. The abstract must incorporate some key points about the review work. I mean overall aspects of the review work must be included.
2. Introduction part needs to be incorporated with carbon fibers for polymer composite applications. See the below works and follow that
https://doi.org/10.3390/polym14061095
DOI: 10.1002/pc.27150
3. There must be proper explanation for each titles mentioned. In title 4 nothing was described.
4. I feel subtopics in the work is really lesser. Add few more sub divisions to make the work better.
5. Is that relevant to use these much of article review. Some works are not used properly.
6. Conclusion must include overall analysis of all the reviews.
