Condensation polymers

Question 1

What two monomers can react in a condensation reaction to form a polymer?

Answer 1

Diols + dicarboxylic acids/diacyl chlorides
Diamines + dicarboxylic acids/diacyl chlorides

Question 2

What are polyesters?

Answer 2

Polymer that contains ester links

Question 3

The repeat unit for a polyester made from a dicarboxylic acid and diol contains…

Answer 3

• Two oxygens
• Two carbonyl groups
• The atoms between the two oxygens
• The atoms between the two carbonyl groups

Question 4

What single monomer can react in a condensation reaction to form a polymer?

Answer 4

Monomer with both carboxylic acid and alcohol

Question 5

The repeat unit for a condensation polyester made from a single monomer contains…

Answer 5

• One oxygen
• One carbonyl group
• The atoms between the two groups

Question 6

carboxylic acid + amine ->

Answer 6

amide + water

Question 7

What is a polyamide?

Answer 7

Polymer that contains amide links

Question 8

Outline the steps to work out which monomers made a polyester

Answer 8

1) Identify ester link
2) Break ester link and separate atoms
3) Add H to O to reform diol, add OH to C=O to refore dicarboxylic acid
