polymers

Question 1

condensation polymers

Answer 1

• bet 2 different mono -each mono have at least 2 FG
  -each FG react with other hroup = forms link

when link forked - water relesed
polyethene = ester like
polypeptide / polyamide = amide link

Question 2

polyamides

Answer 2

reaction bet dicarboxylic acid and diamines

dicarboxylic and diamines = have diff FG at both ends- each forms amide links

Question 3

nylon 6-6

Answer 3

1,6 diaminohexane and hexandioic acid
- strong and resistant to abrasion - cloths, airlags and parachutes

Question 4

Kevlar

Answer 4

benzene-1,4-dicarboxylic acid and 1-4 diaminobenzene
- light and strong = bulletproof vest, car tyres

Question 5

peptides

Answer 5

contains amine functional group and carboxylic acid
- conden R = polyamide
- poly bet AA = peptide

Question 6

polyester

Answer 6

formed by reaction bet
- carboxyl group = diCOOH
- hydroxyl = of diols
form exter link = polyester
