im rlly not sure how to go about this topic, would i ever be expected to draw a polymer such as nylon or can i just familiarise myself with its properties and uses? seems a bit tedious to memorise what each polymer looks like (the addition ones are fine... I'm a bit shit at the condensation ones), but I'm not sure, i just started learning this. thank youuuu

There are multiple different nylons but the main thing is that you memorise the functional group

surely theyre not that cruel that they make us draw the whole polymer right!?!?
lmao u could honestly just memorise 1,6 diaminohexane (just a 6 Carbon chain long hexane wit amine groups on either end) & hexanedioic acid (just carb. acid wit 2 functional groups - one on either side) & then if they EVER ask us to draw it, just remove the OH's from the acid, an H from the amine (thus removing H2O) join em together & there you go (idek if thats the right approach bruh)

i dont actually know what to do, my school decided not to go over it so I'm resorting to other ppls notes so I've never even come across 1,6-diaminohexane but thank u so so much for this ur a lifesaver!!

Polymers Properties

Hi all, This is like the one thing I haven't properly looked at yet and chem trials are on Friday 🤩 Could someone please give a quick rundown of the properties of the different polymers? Maybe how and why they have their properties too...? Thank you! LDPE // HDPE PP PVC PTFE Polystyrene...

also would u ever get asked abt how polymers are formed (like talking abt that free radical stuff)?? bc the syllabus only mentions "model and compare the structure, properties and uses of polymers"

not according to syllabus but we learnt it in class and u should know it anyways it

im going to kill my teacher how much emphasis should be placed on polymer revision? I'm so sorry I'm asking so many questions BUT IDK HOW IMPORTANT THIS SECTION IS

polymers is a section of its own in module 7, i would say you need to know all the basic addition polymers stated in the syllabus + at least one each of polyesters and polyamides - know their monomers, then have 2-3 properties in mind that can be linked to 1-2 uses for each.
you'd also need to know how the addition + condensation polymerisation reactions work and how to apply them beyond the stuff in the syllabus. you could be asked to write out the products of condensation polymerisation given random reactants that you've never seen before

thank you so so much 🫶

@nsw..wollongong i do have revision notes on polymers i made for trials, if you want them
