When checking solubility of my nylon (from lab) I observed that it was NOT soluble in the folowing solvents.Methanol, acetone,diethyl ether,hexane and ethyl acetate.
Cosidering the solubility of the nylon across the dirent solvents, what conclusion could be made about nylon solubility based on the structure of nylon and the structure of the solvents?
