Polymerization
Polyethylene is a thermoplastic polymer obtained by polymerizing ethylene monomer. The ethylene monomer molecule has the formula C2H4 with a double bond between the two carbon atoms (figure 1a). It is thanks to this double bond that polymerization can take place, as can be seen in figure 1b. It's important to note that figure 1b shows only a very small fraction of the long chain made up of carbon atoms: indeed, a polyethylene macromolecule...
