Powerful Proteins

Slimy polymers

PVA (polyvinyl alcohol) is a polymer which is used to make glue. If we mix it with borax, the chains of PVA become crosslinked by the borax. This crosslinking stops the PVA chains moving about so freely, so we end up with a semi-solid. Crosslinking also occurs between the amino-acids in proteins.

PVA and Borax react together to give a crosslinked polyer PVA and Borax react together to give slime!
