Question 9

What bonds are there between polyamides

Answer 9

H bonds

Question 10

What bonds are there between polyesters?

Answer 10

Permanent dipole-dipole forces of attraction

Question 11

Why are condensation polymers used more often than addition polymers?

Answer 11

Condensation polymers are used more often as they are biodegradable and and can hydrolysed. Addition polymers will remain in the environment for thousands of years
