The first answerer means well, but he has no clue as to what you are asking. This equation is related to Carother's equation, which relates degree of polymerization of a step growth polymer like a polyester to the conversion of the functional groups. This particular equation is gives the weight average degree of polymerization as a function of conversion. This derivation is pretty long and complicated; however, T. Lodge of the U. of Minnesota has published a free online book on this subject. See the URL below; what you want is on pages 29 - 33 or so. If you have trouble accessing, contact me via Answers Email.

I suppose that Xw is =y
So dy/dp = (1-p -(-(p-1))/ (1-p)^2 = 2/(1-p)^2
