Polymers

• polymers are made of the same molecules joined together. these polymers make up plastics
• polymers are made up of small molecules called monomers
• monomers making polymers is called polymerisation.
• polymerisation usually happens under high pressures and catalyst
• polymers monomers are often alkenes
• addition polymers are made up of unsaturated monomers
• alkenes open their double bonds and join together to form polymer chains. This is called addition polymerisation.
• Condensation polymers require two functional groups
• two monomers of different functional groups bond together to form a polymer chain
• for each bond a small molecule (Water) is lost
