1
Q
What is the equation and formula for PET?
A
nHOCH2-CO-CH2-CO-CH2OH + nHOCH2-CH2-CH2OH –> (-O-CO-CH2-CO-O-CH2-)n + 2n-1 H2O
2
Q
What is condensation polymerisation?
A
monomers join together with the loss of a small molecule (H2O)
3
Q
What are the types of condensation polymers?
A
Polymers and polyesters
4
Q
What happens in base hydrolysis?
A
R1COOR2 + NaOH –> R1COO-+Na + HO-R2
R1CONHR2 + NaOH –> R1COO-+Na + NH2-R2
5
Q
What happens in acid hydrolysis?
A
R1COOR2 + HCl –> R1COOH + HO-R2
R1CONHR2 + HCl –> R1COOH + N+H3-R2
