Im trying to dissolve PEO Mv= 100,000 in water. Is anybody know what is the approximately range of solubility in water? Should I expect transparent mmix after powder is fully dissolved?
These polymers are amphiphilic and soluble in water as well as in many organic solvents (e.g., methylene chloride, ethanol, toluene, acetone, and chloroform). Low molecular weight (MW
I have notice that after 16 h of mixing in DI water, mix is hazy but without visible powder. After filtration (10 microns) the mix is more transparent. I attached the pic of mix before and after filtration.
However, after 24 h the mix is staring to be hazy again, and probably PEO is coming of from solution. Am I doing something wrong?
