>hello u guys! Damn Nav`a`gator: ![]() ![]() ![]() ![]() Of all the inactives listed above, the methacrylates(Eudragit) will reek the most havoc so it's extremely important that those are removed during extraction or you'll risk coming up empty handed. Check this out first... SYNTHESIS OF A NEW FAMILY OF POLYELECTROLYTES FROM IONIC METHACRYLATES (single page PDF fie) ![]() Then review Prepuce's Gakinator thread.Post 512919 (Prepuce: "Gakinator?", Stimulants) Barkingburro's thread Post 515327 (barkingburro: "first experiment in throwing eudragit a success", Stimulants) And also Uncle Fester's thread Post 499089 (UncleFester: "deconstructionist thought", Stimulants) (I'd have listed U_F's thread first if he wasn't so modest, timid, and unsure of himself ![]() ![]() ![]() For the Standards Data and Application Technology Sheets concerning the Eudragit® family of Gaaks see my thread Post 494861 (wareami: "Eudragit", Stimulants)(read the 1st 4 PDF files in that thread) I'll be a good bee and post this info here!
