How do polymers dissolve

WebMay 7, 2024 · How do Polymers dissolve in water? The polymers consist of long strands of molecules covalently bonded (or cross-linked) together. The strands form hydrogen bonds with water, while the cross-links prevent the polymer from dissolving in the water. Depending on the precise structure of the polymer, the process may occur quickly or slowly. WebStep 1: Preparing the Balls As you may or may not know you place the polymer balls in water and let them absorb as much as they can hold until you finish with nicely rounded, much larger balls. I let mine sit over night since I put them in late and woke up to exactly what I expected. Ask Question Step 2: Which Holds the Dissolving Power?
