module 6 - condensation polymers

Question 1

condensation polymerisation

Answer 1

the joining of two monomer with loss of a small molecule, usually water

Question 2

polyesters

Answer 2

• can form from a dicarboxylic acid and diol or a monomer with both a carboxylic acid and alcohol functional group.
• this forms an ester linkage

Question 3

polyamides

Answer 3

• can form from a dicarboxylic acid and diamine or one monomer with both functional groups
• forms an amide linkage

Question 4

hydrolysis

Answer 4

-hot aq alkali or hot aq acid

Question 5

hydrolysing polyesters

Answer 5

• base hydrolysis (NaOH and H2O) forms a carboxylate salt and an alcohol
• acid hydrolysis (H+/H2O) forms an alcohol and a carboxylic acid

Question 6

hydrolysing polyamides

Answer 6

• base hydrolysis (NaOH/H2O) forms a carboxylate salt and an amine
• acid hydrolysis (H+/H2O) forms an NH3+ ion thing and carboxylic acid
