Alright, so we want to give the monomers that produce these polymers, and the first polymer is, well, section of the polymer, is a six -carbon chain with a benzene ring on every other carbon, as well as a methyl group.
00:27
So i'm going to use a circle with a line -throat to represent the benzene ring, and the other carbons just have hydrogens.
00:41
And this is only section of the polymer.
00:42
It continues for however long.
00:48
So this is an example of, in addition, polymerization reaction.
00:51
It takes place between.
00:52
An alken and a radical generated from some side reaction one possibility is the peroxide radical but we're going to start with a two carbon alken which is ethylene and um this carbon is ch2 so we can just add hydrogen to this carbon but the other carbon is going to have a phenyl ring and a methyl group so one possibility is the peroxide radical and the presence of heat uvulite or pressure the oxygen oxygen single bottle is going to break it's very stable and each oxygen will get an electron.
01:32
This will give us two oxygen radicals.
01:34
And the one oxygen radical is going to attack the less standard of carbon, which is this one be this one's ch2.
01:43
So forming a bond with that carbon.
01:45
And as a result, this carbon gets radical.
01:49
And this is going to be carbon one and two.
01:52
And just drawing the ether first, which is ro.
02:00
There's carbon one, and two has the methyl and the benzene ring.
02:10
And this is going to be the monomer.
02:12
So if you wanted to write a formula for this, we have two carbons of the alken.
02:19
We have a methyl.
02:20
So three there, six in the ring.
02:23
And so we have nine carbons...
