In this paper we would like to give a brief review about the extensibility of the liquid-liquid locus into the negativepressure region. Negative pressure states are hardly explored; most researchers believe that the pressure scale ends at p = 0.We would like to show that this is not true

it can be "easily" crossed. We aregoing to give a few example
where the extension of liquid-liquid locus for polymer blends and solutions below p = 0 gives us some interesting results
like the merging of UCST and LCST branches in weakly interacting polymer solutions of the reason why most UCST blends exhibit pressure induced immiscibility.Also we will see what happens with the immiscibility island of aqueous polymer solutions when—reaching the critical molar mass—it"disappears".
