Review of 'Dynamic Covalent Cross-Linked Network Based on A: Synthesis, Properties, and Shape Memory Function'

This article mainly utilizes 'A' as a novel monomer for preparing a dynamic covalent cross-linked network and investigates its mechanical properties, thermal properties, and shape memory function. However, there are some issues with the paper that I suggest be addressed before it can be accepted by the journal. The problems are as follows:

1. The author mentions the hardness and toughness of the material in the abstract, but rarely discusses them in the main text.
2. It is recommended to use the same name for the same substance in the main text. For example, the author uses both 'methyl tetrahydrophthalic anhydride' and '3a-methyl-5,6-dihydro-4H-isobenzofuran-1,3-dione'. Additionally, MTHPA and MeTHPA are used interchangeably.
3. Figure 1 does not appear in the main text or have any explanation.
4. The model of the testing instrument used should be specified in the main text.
5. It is suggested that the author test the glass transition temperature of the material.
6. The content of section 3.2 seems to be incomplete.
7. In Figure 6, why does HMY1 require less bending stress under the same bending strain?
8. In the conclusion, the last paragraph is in a different font from the preceding text and seems somewhat redundant. It is recommended that the author remove it.
