Oxygen and Nitrogen based Polymers

Question 1

name 2 Nitrogen based polymers and 4 oxygen based polymers?

Answer 1

N- Polyamide N- Polyaramid O- Polycarbonate (PC) O- Polyethyleneterephthalate (PET) O- Polylactic acid (PLA) O- Polycaprolactone (PCL)

Question 2

What properties arise by having Nitrogen in the polymer backbone?

Answer 2

• lower resistance to acids - Stronger IM forces between chains, so higher Tmelting - yellowish colour especially with benzene groups

Question 3

what properties arise by having Oxygen in the polymer backbone?

Answer 3

• lower resistance to organic solvents - more prone to oxidation/hydrolysis - stronger IM forces between chains, so higher Tmelting and Tg - Presence or aromatic groups in backbone increases rigidity, so tough and creep less

Question 4

Describe the structure of Nylon 6 and Nylon 6,6
