Answer 2

long chain of small molecules or monomers

Question 3

What are the 2 types of polymerisation?

Answer 3

addition or condensation

Question 4

In addition polymers, what are the monomers?

Answer 4

alkenes

Question 5

When drawing addition polymers, why do we place an ‘n’ outside the brackets?

Answer 5

indicates that polymer contains large no. of repeating units
