Answer 8

polymerisation

Question 9

What is usually needed for polymerisation to happen?

Answer 9

A high pressure and a catalyst

Question 10

What happens during polymerisation?

Answer 10

During polymerisation the monomer molecules join together end to end.

Question 11

What is addition polymerisation?

Answer 11

Addition polymerisation is the type of polymerisation involving alkene monomers.

Question 12

What happens during addition polymerisation?

Answer 12

during addition polymerisation unsaturated monomer molecules react together to form a saturated polymer molecule.
