Polymer: A polymer is a generic term used to describe a substantially long molecule. This long molecule consists of structural units and repeating units strung together through chemical bonds. The process of converting these units to a polymer is called polymerization. These units consist of monomers, which ...

Condensation polymer: Condensation polymers are any class of polymers formed through a condensation reaction, as opposed to addition polymers which involve the reaction of unsaturated monomers. Types of condensation polymers include polyamides, polyacetals and polyesters....

Ester: In organic chemistry and biochemistry, esters are organic compounds where an organic group (symbolised by R' in this article) replaces a hydrogen atom (or more than one) in an oxygen acid. An oxygen acid is an acid whose molecule has an - group from which the hydrogen (H) can dissociate as an H+ io...
