1. Widespread polymers
The crude oil refining flowchart (Figure 1 ) shows that during steam cracking, naphtha from atmospheric distillation and heavy products from vacuum distillation are used to ultimately produce:
ethylene, a monomer of polyethylene;
propylene, a monomer of polypropylene;
benzene, a monomer of polystyrene.
These three materials are by far the most widely used in the packaging industry.
The table at 1 complements this diagram by showing that, regardless of the origin of the raw materials (coal, gas, oil), the process goes through the "major intermediates"...
