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. WebSlime is sometimes described as a reversible cross-linking gel. The cross-linking between the polymer chains of polyvinyl alcohol occurs by adding borax, Na 2 B 4 O 7.10H 2 O (sodium tetraborate).
