Name the polymer formed from ethene
WitrynaThis 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. WitrynaPolymer Properties Uses; Low density poly(ethene), LDPE: Flexible, unreactive, can be made into films: Most carrier bags, bubble wrap: High density poly(ethene), HDPE

Propene will react with steam to form two isomers, both of which are alcohols. Suggest the structures of these alcohols. WitrynaAddition polymers are made from molecules containing C=C bonds. Polymers have different properties and uses but it is difficult to dispose of them. DNA, starch and proteins are biological polymers.
WitrynaProcedure. Prepare a 250 cm 3 beaker of boiling water to act as a water bath. If using a Bunsen burner, keep all other chemicals well away from the flame. Add 0.1 g of di (dodecanoyl) peroxide to 5 cm 3 of phenylethene in a boiling tube. Fit a bung carrying a 20 cm length of glass tubing in the top of the boiling tube. WitrynaPolymers made in this way are called addition polymers. The monomers used to make other addition polymers are drawn in a similar shape to ethene, for example, propene.

Witrynaethene molecules can be joined together to form a polymer. The polymer is called poly(ethene) because it is made from ethene. This is an example of addition polymerisation. Poly(ethene) is commonly called polythene. Polythene is an ICI trademark for poly(ethene).
