Bonding in polymers
1. Describe the structure and bonding in polymers.
• Polymers are made by joining together thousands of small, identical molecules (monomer).
• Monomers are often alkene molecules eg. ethene.
2. Explain why polymers are solid at room temperature.
• Most polymers are solids at room temperature.
• The intermolecular forces of attraction between polymer molecules are relatively strong so it takes a lot of energy to break these forces.
Addition Polymers - Polymerisation of Ethene
Ethene → polyethene
Two types of polyethene - LDPE and HDPE
Polymerisation of propene & chloroethene
How to write equations for the formation of polychloroethene and polypropene?
chloroethene → poly(chloroethene) also known as PVC
propene → polypropene Uses and Problems of Polymers
Learn about some polymers, their uses and problems associated with them.
