My Second Ideas to Try
Degrading PEO: Idea 1
Degrading the PEO will release the oxy from a pill. One way to degrade it is through shear forces. I did a little research and found this graph on how shear rate sky-rockets when forcing a liquid through a small pipe at a high speed.
Graph: Shear Rate
An interesting experiment would be to turn your OP into a very fine powder, add that powder to some 100% IPA. Next, you would need to build a small liquid pump that feeds itself or pumps the IPA solution in a circle at a fairly high pressure. Perhaps a fountain pump might work here? Fish tank pump? The chart above shows how a high-flow plus a small pipe will cause extreme shear forces. A few hours, or even minutes, might be enough stress to degrade the PEO to PEG, and cause the oxy to become sediment.
A good experiment would stop every 5-10 min and take a picture of the amount of sediment that has been released.
Degrading PEO: Idea 2
A ghetto version of this might be to make a very fine powder, add a small amount of 100% IPA to make a paste. Then use a mortar and pestle to grind the fuck out of it for several minutes. Add to more IPA, let sit. See how much sediment is released.
Degrading PEO: Idea 3
Last, in Purdue's patent they show a 70% IPA solution caused 35-45% release of the oxy. We know the PEO will dissolve in IPA (but they used 70%, not a good choice) and, most importantly, IPA doesn't degrade the PEO (which is the key to extraction) because many people have tried IPA and no one has had a successful extraction.
So why did they have 35-45% success with a 70% IPA solution made from a poorly-milled (not very fine) pill? Because they used a constant-stirring device for 60 minutes which broke down the PEO and released the oxy! This needs to be tried: someone grinds the pill VERY fine, uses 100% IPA to prevent gelling, and then uses a magnetic stirrer (or some other way of stirring very vigorously) for a few hours. Maybe then we could achieve a higher percent, evaporate the IPA, and have our extraction method!
