Acaicia,
Generally people with knowledge that would be useful towards answering your question would not be inclined to. Sorry! Here are the reasons:
1) You are new here, we don't know who you are or where you are from.
2) For those in the know, open discussions about formulation of propellants generally falls under US regulations such as ITAR. It is even a specific line item in the regulations! Anyway a discussion on technical info that can be observed/obtained by a non-US citizen or dual citizen or a US citizen working for a foreign government or corporation or interest, is considered an export. Essentially the answer to your question may qualify as an arms export, legally, in the US. That requires major high level approval...
3) There are exceptions for research. There are lots of research papers online. Suggested background in physics, chemistry, engineering, math. And for binders, some knowledge of organic chemistry. It's an inter-disciplinary problem, and gets the label "rocket science" as overall it is fairly complex, and very non-forgiving of mistakes.
4) Mistakes can result in death and destruction. Very unfortunate for those involved. Also can be very unfortunate for those not involved, like the other people who enjoy this hobby. So we tend to get a bit protective on occasion.
5) So we don't like to get into propellant manufacturing discussions with those who have not already proven themselves capable of working safely and responsibly, through a track record of demonstrating competence with commercial motors.
Specifically when it comes to binders, before you go exploring too much, you should study up on it enough to know why the current binders are the current binders. That is, what makes them good for the job, and lots of other potential options not necessarily so good? When you can answer that, you might be ready for the research phase of your quest.
That's the short answer. I hope you stay around as rocketry really is fun and can be as deep as you want to make it.

PS - Youtube is a good place to learn all the wrong techniques. It is full of dangerous idiots.
