Polymers and monomers in chemistry HELP PLEASE!!Watch this thread
I’m trying to do my chemistry homework and I am really confused as to how they work. How does a monomer turn to a polymer and what exactly even are they and how do they occur. And if I was given a question for example to show the displayed formula of polystyrene as a monomer and a polymer?
Now let's think of polystyrene:
It is called an addition reaction.
Others are easier to do e.g. polypeptides / polyamides or polyesters are formed by condensation reactions
Here, in the monomer (ethene), there is a double bond.
In the addition reaction (which only occurs in certain conditions), the double bonds break so that bonds between the monomers can form to produce a polymer (shown as polyethene).
This is addition polymerisation.
