Question: what is the chemical reaction between glue and borax?
Answer: Silly Putty: Synthesizing a Polymer Adding Elmers School glue (or generic brand School Glue) to a water/borax solution causes a chemical reaction between the glue molecules (polyvinylacetate) and the borax molecules (Na2B4O7 •10H2O) to produce a highly flexible, cross-linked polymer.
