Ethylene glycol and terephthalic acid.
Ethylene glycol and terephthalic acid.
See lessDefine the term polymerisation.
Polymerization is the process of forming high molecular mass (103 − 107 u) macromolecules, which consist of repeating structural units derived from monomers. In a polymer, various monomer units are joined by strong covalent bonds.
