- Polymers
- Polymers are many monomers in a long chain
- When a monomer is turned into a polymer it is called polymerisation
- The double carbon carbon bond in the monomer opens up to become a single bond and many join up in chains as a polymer
- When a monomer is turned into a polymer it is called polymerisation
- A thermosoftening polymer can soften when heated and remoulded
- Forces between the chains are weak so are easily broken and the polymer softens
- As it cools the intermolecular forces bring the polymer molecules back together so it hardens
- Forces between the chains are weak so are easily broken and the polymer softens
- A thermosetting polymer does not melt or soften under heat
- Forces between the chains are very strong as they are covalent bonds form cross links between the chains
- Low and high density polymers can be made using different catalysts and reaction conditions
- High density polymers have a higher softening temperature and are stronger
- Polymers are many monomers in a long chain
