Polymers are extremely large molecules fomed from many repeat units of smaller molecules (monomers). unsaturated alkene molecules undergo addition polymerisation= produces long saturated chains (no double bonds)
-
- a repeat unit is the specific arrangement of atoms that repeats over and over
- the repeat unit is always written is square brackets
- addition polymers have large molecular masses
- synthetic polymers are named after the monomer that reacts alongside the prefix 'poly'
- polyethene is the most common e.g. supermarket bags, shampoo bottles
- polychlorothene/poly vinyl chloride (PVC) can be prepared to make ampolymer that is flexible or rigid.
