Poly ethene formula
WebTHE POLYMERISATION OF ALKENES. This page looks at the polymerisation of alkenes to produce polymers like poly (ethene) (usually known as polythene, and sometimes as polyethylene), poly (propene) (old name: polypropylene), PVC and PTFE. It also looks briefly at how the structure of the polymers affects their properties and uses.
