CHEM - Addition Polymer
Chemistry, addition polymer, organic chemistry - IGCSE | IBDP | DSE | GCE | IAL | AP Chemistry
👇 For example, many ethene monomers join to form poly(ethene). 👇
As you can see, poly(ethene) is basically the repetition of the repeat unit. Since poly(ethene) is a very large molecule, we can just draw the repeat unit to display the formula.
Drawing Repeat Unit of Polymers
When drawing the repeat unit from an alkene monomer,
For IGCSE Chemistry, you should be able to draw the repeat unit of poly(ethene), poly(propene), poly(chloroethene) and poly(tetrafluoroethene).
👇 Poly(chloroethene) 👇
👇 Poly(tetrafluoroethene) 👇
Problems in the Disposal of Addition Polymers
Addition polymers are inert and unreactive, so they are non-biodegradable. It means they cannot be biologically decomposed by microorganisms.
Problems associated with the two methods of disposal of addition polymers:
