Gcse chem help? <33

Hey, I was wondering if I could have some help- I was a bit confused in some Chemistry, as monomers are shown to have these double bond things (looks a bit like this =), but when you have to draw out the polymer diagram for it, it only has a single bond to it? Do we have to know the reason or is it above GCSE level? (I do combined btw)

THANK YOU SO MUCH

THANK YOU SO MUCH

That double line is a double covalent bond between the 2 carbons in the monomer. In addition polymerisation, you break the double bond to single bonds in the monomer, so different monomers can connect together (as carbon can form 4 bonds). When you draw the polymer, you just draw 1 repeating unit (so get rid of the double bond in the monomer to make it a repeating unit) in the polymer, with n stating how many repeating units.
