Polymers Properties (2 Viewers)

[SadCeliac]

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! <3


UPDATED WITH SUMMARY

textbook


ADDITION POLYMERS
Polyethylene --> LDPE // HDPE
PP
PVC
PTFE
Polystyrene
Acrylic
PVA

CONDENSATION POLYMERS
Polyester --> ester bonds
Nylon --> amine bonds

 

[SadCeliac]

its pretty obv tho
LDPE : PLASTIC BAG WHAT R THE PROERPTIES OF T PLASTICS BAG
HDPEl; PRPERTIES OF A CHOPPING BOARD
POLYTETRAF: WAHT R THE PROPERTIES OF THE LUBRICATING THINGS
POLYETHYENLYBETZNESE OR SYTRNE: DO YOU NOT KNOW WHAT POLYSTYRENE IS ALR JUST TALK ABOUT THAT
VINYL CHLORDIDE: SEWAGE PIPE PROPERTIES UNLESS U ADD PLASTICISERS
NYLOa6^6: U KNOW WHAT NYLON IS FROM REALI LIFE
PET: YOU ALSO KNOWW

THANKS BUT WHY DOES THIS HAPPEN

THANKS BUT WHY DOES THIS HAPPEN

STRONG = LOTS OF INTERNOLECULAR AND TIGHTLY PACKED (JUST LOOK AT STRUCTURE TO SEE)
HIGH BP = LOTS OF INTERMOLECULAR FORCES
POLAR = LIKES WATER (LIKE SOAP)
NONPOLAR = HATES WATER (ALSO LIKE SOAP)

OKAY COOL BUT WHAT ABOUT STUFF LIKE PVC??? IS THAT BECAUSE THE CHLORINE DOES SOMETHING

 

[carrotsss]

OKAY COOL BUT WHAT ABOUT STUFF LIKE PVC??? IS THAT BECAUSE THE CHLORINE DOES SOMETHING

PVC = LOTS OF DIPOLEDIPOLE(ELECTRONEGATIVE CHLORINE) AND DISPERSION = HIGH BOILING POINT AND STRONG
NOT MANY PLACES TO REACT SO IT DOESNT REALLY REACT MUCH
ADD OTHER THINGS TO GIVE IT ALL DIFFERENT PROPERTIES TO MAKE IT MORE RIGID OR FLEXIBLE OR WHATEVER U WANT

AHHHH OKAY THANK YOU THANK YOU

WAIT SO WHAT ARE THE KEY ONES I NEED TO KNOW???
LDPE- PLASTIC BAG
HDPE- HARD PLASTIC
PVC-
STYRENE-
....

ALSO WHICH ONE IS THE ONE WITH THE BENZENE RING???

bro why tf don't i just google this

im just gonna make a summary then post it here for yall to check <3

YOU ONLY REALLY NEED TO WORRY ABOUT PE PVC PS AND PFTE THE REST ARENT DIRECTLY IN THE SYLLABUS

OKAY THANKS

I MAY AS WELL LEARN ALL OF THEM THOUGH

WAIT WHICH ONE IS NYLON??

 

[carrotsss]

OKAY THANKS

I MAY AS WELL LEARN ALL OF THEM THOUGH

WAIT WHICH ONE IS NYLON??

NYLON AND POLYESTER ARE THE CONDENSATUON POLYEMRS

 

[SadCeliac]

NYLON AND POLYESTER ARE THE CONDENSATUON POLYEMRS

OHHH OKAY YEAH FORGOT ABOUT THOSE

AND I JUST NEED TO REMEMBER WATER IS A BYPRODUCT OF CONDENSATION??

 

[synthesisFR]

I MAY AS WELL LEARN ALL OF THEM THOUGH

go ahead waste ur time

the the question asking abt other polymers gives u diagrams and makes u apply what u know e.g condensation u remove OH and H and blah blah

YEAH PRETTY MUCH THATS IT

yeah nah there's been like three or four questions ive run into that go into "explain how the properties of polymer blah blah make it strong"

 

[synthesisFR]

yeah nah there's been like three or four questions ive run into that go into "explain how the properties of polymer blah blah make it strong"

show us

yeah only the ones in the syllabus through

 

[SadCeliac]

show us

suree




parts (a) and (b) were easy
part (c) I just skipped (looking back at it I probably could have done it)

its literally in the syllabys tho
