Monomers, polymers and addition polymerisation
Monomers, polymers and addition polymerisation

Synthetic polymers are giant molecules made when many small molecules called monomers join together. Many familiar plastics are synthetic polymers because long chains give useful properties such as strength and waterproofing.
Step-by-step lessons on Edexcel IGCSE Chemistry Synthetic polymers. Each one builds up to exam-style questions. Build a solid grasp of atomic structure, bonding and the mole concept early, since these underpin almost every other topic, then move on to the more calculation-heavy quantitative and organic chemistry content.
