[edit] Ideal mix

If anyone has an example of a polymer whose monomers form an ideal mix with its solvant, or an experiment where a polymer behaves in some way or the other like an ideal chain, that'll be great.ThorinMuglindir 10:41, 29 October 2005 (UTC)

Hi

There is an sever Error in the Artikel The End to End distance is Normal distributed, but the End-to-End Vektors are NOT! There you have to take into account, that the Ammound of vectors with a certain end to End distance R is Proportional to the Survace of an Sphere with the Radius R so the Korrekt Formular is

<\math> P(R)=\left ( \frac{3}{2 \pi N l^2} \right )^{3/2}e^{-\frac{3 \vec R^2}{2 N l^2}}</math> or <\math> P(\vec R)=\frac{\left ( \frac{3}{2 \pi N l^2} \right )^{3/2}}{4\pi R^2}e^{-\frac{3 \vec R^2}{2 N l^2}}</math> [[User:Patrickruediger, 10:04, 7.December 2006

[edit] Probability distribution

It may be worth noting that the probability distribution given in the article is only true for the end-to-end vector in the thermodynamic limit. The exact solution is dimension-dependent and can only be given as a series solution. See Yamakawa 'Modern Theory of Polymer Solutions' (1971, Harper and Row) for the complete derivation.
