I have been considering make a small batch of copper benzoate to experiment with its use a fuel in whistle compositions. I have opted not use ammonium perchlorate since I do use potassium chlorate for a few things, so a few AP compositions are out.

Bit of a thread necro but I felt this needed to be added:

 

I was able to find the resin he mentioned: http://encyclopedia2.../Phenolic Resin

 

That page is an entry from The Great Soviet Encyclopedia (1979). It contains the exact image OP posted for his resin. It appears to be a novolac resin. Wikipedia says the following:

 

 

Hexamethylenetetramine or "hexamine" is a hardener added to crosslink novolac. At a temperature >90 °C, it forms methylene and dimethylene amino bridges. -https://en.wikipedia..._resin#Novolacs

 

Here all of the formulas given directly:

 

(AP = Ammonium Perchlorate; KP = Potassium Perchlorate; NC = Nitrocellulose; SrN = Strontrium Nitrate; BaN = Barium Nitrate; Hex = Hexamine; Phenol = Novolac/Phenolic formaldehyde resin; CuCl = Copper (I) chloride; NaOx = Sodium Oxalate)

Phenolic resin has been used for quite some time especially by the Chinese and some other countries. It's only fairly recently becoming popular in the US.

It can be found but James Widmann of WASP fame that owns CTpyro for selling his machines has imported a lot from China and has been selling it for a few years. It also works with hexamine to cure the resin where it can be used in large comets that cure/dry/harden quickly as opposed to having to wait for a solvent to evaporate.

Anyways, just a bit more info on phenolic resin.

Edit: more info
