Dear friend Akram Almahmodi

Both sebacic acid and sebacoyl chloride can be used as monomers for the synthesis of Nylon 6,10. However, the choice of monomer can affect the properties of the resulting polymer, including its latent heat.

Sebacic acid is a diacid monomer, which means it has two carboxylic acid groups. These groups can react with the amine groups in hexamethylenediamine (HMDA) to form Nylon 6,10. Sebacoyl chloride, on the other hand, is a diacid chloride monomer that can be used to form Nylon 6,10 by reacting with HMDA. Sebacoyl chloride can be more reactive than sebacic acid, which may affect the amount of monomer needed for synthesis.

To increase the latent heat of Nylon 6,10, the amount of sebacic acid or sebacoyl chloride used in the synthesis can be adjusted. Generally, increasing the amount of monomer can increase the amount of crystallinity in the polymer, which can increase its latent heat. However, adding too much monomer can also lead to issues such as decreased polymer yield and decreased thermal stability.

It is also important to consider other factors that can affect the properties of Nylon 6,10, such as the reaction conditions (temperature, time, solvent, etc.) and the purity of the monomers used.

Here are some references that may be helpful in understanding the synthesis and properties of Nylon 6,10:

Dear doctor Kaushik Shandilya,

Thanks for you answer. The problem i am facing now is that there is a lake of papers on Nylon 6,10 and all available papers are on sebacoyl chloride not sebacic acid. I also still can not find the mentioned references

Dear friend Akram Almahmodi

I understand that you are specifically looking for research papers on Nylon 6,10 synthesized from sebacic acid instead of sebacoyl chloride. It can sometimes be challenging to find literature on specific variations or modifications of materials, especially if they are less commonly studied. Here are a few suggestions to help you find relevant information:

1. Expand your search terms: Try using alternative keywords or variations in your search. Instead of searching for "Nylon 6,10," you can try searching for "polyamide 6,10," "PA 6,10," or "polyhexamethylene sebacamide." Additionally, include specific terms related to the synthesis method or starting materials, such as "sebacic acid," "polycondensation," or "polymerization."

2. Broaden your search scope: Instead of limiting your search to academic papers, consider looking for patents, conference proceedings, technical reports, or dissertations. These sources may contain valuable information on specific variations of Nylon 6,10.

3. Explore related literature: Although you may not find papers specifically on Nylon 6,10 synthesized from sebacic acid, you can look for studies on other polyamides or related materials that may provide insights into the synthesis, properties, or characterization techniques applicable to Nylon 6,10. This broader understanding can still be useful in your research.

4. Contact experts in the field: Reach out to researchers or experts in the area of polymer chemistry, specifically those working with polyamides or Nylon materials. They may be able to provide guidance, share unpublished information, or suggest alternative sources for your specific research interest.

5. Collaborate with peers: Engage with fellow researchers, attend conferences, or join online forums related to polymer chemistry. Networking with peers who have similar research interests can help you find relevant literature or exchange knowledge on specific variations of Nylon 6,10.

Remember, research is an iterative process, and sometimes finding specific information can be challenging. It may require a combination of creativity, persistence, and collaboration to address gaps in the literature.
