anyone ever heard of polyphosphorous?????

Linear PolyPhosphorous Acid is used in Plant Nutritional Activator/Soil Amendment

That's all I could find about it. Why do you ask?

just wondering if this could be used to skip a step in the red phosphorous extraction. Been doing alot of research and this came across my screen. Curiosity got the best of me so i brought it to the only people i know that know anything. Thanx for the input

probably not, as polyphosphorous acids are not true phosphatic acids, sodium tripolyphosphate could somehow be stripped to be used but not by itself.

you would probably want to look into hypophosphorous acids/phosphorous/phosphoric acid to replace rP in some instances.
