Polymer is water-soluble at room temperature, insoluble above ~40º . Solubility ceiling has
been used in mold and cell growth techniques since cells adhere to polymer film at incubation
temperatures and are released as medium is cooled and polymer is dissolved . Soluble in: THF,
dioxane, DMF, cold water, chloroform .
