formed when lots of small
molecules join together
- A substance made of
macromolecules
- Synthetic

Polymerisation
- Double bonds in
molecules break & they
add on to each other
- Monomers must
have C=C double
bonds
- Condensation
Polymerisation
- Two different
monomers join
- Each has 2
functional groups
that take part in
reaction
- Monomers join at
functional group by
eliminating small
molecules
- Plastics
- Insulator
- Unreactive
- Strong
& light
- Some
non-biodegradeable
- Macromolecules
in Food
