How are synthetic plastics made
WebIt is made by copolymerizing ethylene with 1-butene and smaller amounts of 1-hexene and 1-octene, using Ziegler-Natta or metallocene catalysts. The resulting structure has a linear backbone, but it has short, uniform branches that, like the longer branches of LDPE, prevent the polymer chains from packing closely together. WebSynthetic polymers like polyethylene (PE), polypropylene (PP), nylon, polyester (PS), polytetrafluoroethylene (PTFE), and epoxy (commonly known as plastic) are derived from petroleum hydrocarbons [1]. These polymers are an incredibly versatile group of compounds—so versatile, in fact, they can be found in all sorts of unexpected places.
