Abstract: In this study we investigated the mixing behavior of the Gemini
surfactants (T11H1SnH1T11 ,n=2,4,6,8) and oils (Tn ,n=2,3,4 ) in aqueous
solutions by using lattice Monte Carlo simulation method. The results show
that adding oil to the surfactant solution results in decreasing the CMC.
Investigating the changes of the CMC vs. the spacer length shows that

This can be achieved in many ways including the addition salt, which takes
away the water molecules surrounding proteins in solution (as the salt
concentration increases, more water molecules associate with the salt ions
instead of the proteins) and as a result the protein molecules come together
since less water is present between them. From this simple definition you

Chenchuan is right. DMSO is a better solvent for homoPVA, since PVA dissolves
much faster than in water (as I observed). One more fact:
polyisobutylene-b-poly(methyl vinyl ether) is soluble in water when DPn of PIB
is 50 and DPn of PMVE is 260. (PMVE is water soluble). Seems two factors work
together resulting the insolubility of the PIB-PVA in water: "This additional
kind of long range
orderness (from PIB) will make it more difficult to be attacked by solvent";
