Polymers Flashcards
What are polypeptides made of
Amino acids
What are polyamides made of
Diamine and dicarboxylic acid

Diol and dicarboxylic acid
What link do polyamides and polypeptides contain
-CONH-
What link do polyesters contain
-COO ester link
What type of polymer is kevlar
Polyamide
What type of polymer is terylene
Polyester
Properties and uses of kevlar
Lightweight but strong
Bulletprood vests and car tyres
Nylon 6,6 properties and uses
Strong robust fabric
Ropes, carpets and clothing
Terylene use
Plastic bottles
If a polymer is eaisly hydrolysed does this mean that it will be easy to biodegrade
Yes
Where is the polarity in polymers
On polar C=O and C-N bonds
Which type of polymer is stronger and why
Condensation
Delta charged molecules due to polar bonds mean that hydrogen bonds form within parts of the chain increasing BP and strength
Which type of polymer breaks down more easily in water and why
Condenation due to their polar bonds
General uses of condensation polymers
- Non stick pan coatings
- Plastic bottles
- Fabric
