MAKING POLYMERS AND PLASTIC - Paprec

POLYMERS. Before looking at the actual manufacturing process, let us describe in more detail the polymers, these long chains of basic molecules (monomers) made of carbon atoms onto which other elements can be fused through certain chemical reactions, elements such as hydrogen, chlorine, nitrogen, fluorine, or oxygen.

Styrene - Wikipedia

Styrene is also co-produced commercially in a process known as POSM (Lyondell Chemical Company) or SM/PO for styrene monomer / propylene oxide. In this process ethylbenzene is treated with oxygen to form the ethylbenzene hydroperoxide. This hydroperoxide is then used to oxidize propylene to propylene oxide. The resulting phenylethanol is ...
