When reaction acrylic acid into PAA, there is only marginal viscosity increase observed. However out of the reactor, the samples quickly turn from a deposit or an opaque mass. I know now this is normal for PAA and pH-dependent. I am looking for articles that report on these phenomena.
Yes, go this website and download the rheology program,

Dear prof Gooch,
At first, thanks for your answer. I tried in several ways to access your calculation software. and only now I have succeeded in that, from my new home laptop computer. However, I can not find poly-acrylic acid in these systems. Are you sure that it must be in the list of polymers of known rheological behavior?
Dear Inge-Willem
I hope that this article will be helpful: G. Staikos, G. Bokias, The intrinsic viscosity of poly(acrylic acid) ....Polymer Int, 1993, 31, 385-9
Dear Gregory Barshtein,
I found the article from our library database. It looks like to be of great help indeed. Thank you!
