Reddit mentions of Essentials of Polymer Science and Engineering

I worked with just this.

I never found a single best book. Use a combination of:

• ASTM Standards
  
  
• Research papers where people worked with specific polymers (I made my own spreadsheets with properties and profiles from various papers and resources)
  
  
• company documentation (suppliers and etc GELEST has some pretty good stuff for silicones)
  
  
• basic polymer science (this book is pretty good: https://www.amazon.com/Essentials-Polymer-Science-Engineering-Painter/dp/1932078754)
  
  
  If you find a single good resource I'd love to know. I ran TGA on silicone and epoxy nanocomposites daily for 3 years. I also conducted thermal conductivity testing with a custom setup. If you know the polymer chemistry you should be able to figure out the TGA profiles. However, thermal analysis alone is not sufficient if you don't know what's in your sample, you need at a minimum also FTIR (and possibly NMR and raman)
  
  I used a combination of FTIR and TGA to answer questions about my materials, determine grafting density (polymers grafted to the ceramic nanoparticles) and more.
  
  Good luck!
  
  
  EDIT: I sifted through stacks of books at our university library and they rarely had what I was looking for. For your case that might be different.
