The unique coordination-unsaturated Co O 5 single-site can coordinate with the carbonyl groups in polyester, thus boosting the nucleophilic addition elimination processes. 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.
