Synopsis
When two polymers are miscible it is normally because they are of low molecular weight, because they are similar chemically, or because they exhibit specific interactions of an electron transfer nature. Various theories exist which describe the phenomena of polymer miscibility but because they do not directly address themselves to the problem of specific interactions they do not necessarily represent the properties of such systems adequately.
Examples are given of how theory can predict the phase diagrams of mixtures and the effect of variables such as molecular weight, chemical composition and external pressure on the phase diagrams. It is shown that in some cases theory works quite well but in others it fails badly to conform to the observed behaviour. This can be understood when one considers how the specific interactions contribute to the properties of the various mixtures.
