2. POLYMERS

3. POLYMERS
polymers – molecules where many
subunits are linked in a long chain
monomers – subunits which can be
combined to produce a polymer
polymerization – the process of
creating polymers by reacting
monomers together

4. POLYMERS
Two main reactions tend to be used
to produce polymers:
1.addition reactions
2.condensation reactions

5. POLYMERS
Addition Polymers
a) polypropylene

6. POLYMERS
Addition Polymers
b) polyvinyl chloride

7. POLYMERS
Addition Polymers
c) polystyrene

8. POLYMERS
Condensation Polymers
nylon

9. POLYMERS
Strengthening Polymers
The polymers shown cannot withstand a lot
of strain, why not?
crosslinking – a small percentage of
monomers are added to reactions such
that they are able to bond to two
polymers strands

10. POLYMERS
Crosslinking

11. POLYMERS
