WebFormation of Polyesters. They are made using monomers that have C-C double bonds joined together to form polymers such as (poly)ethene. A small molecule (eg. a water molecule) is lost when the monomers join together to form a polyester. This polymer structure shows an ester functional group linking monomers together. WebPolymers as non-solvent based adhesives. Many adhesive products contain a soft polymer with a solvent; When applied to a surface, the solvent evaporates leaving the polymer residue on the surface; Adhesives without the solvent has become a widely used alternative; Epoxy resin and superglue are 2 examples of a non-solvent based adhesive; Epoxy resin
