Worked Solution & Example Answer:The structures of two commercially significant monomers are shown - HSC - SSCE Chemistry - Question 17 - 2004 - Paper 1
Step 1
Step 2
Discuss this statement with reference to a polymer made from one of the above monomers.
Answer
Polymers exhibit a range of properties that are directly influenced by their structure and the nature of their monomers.
When considering PVC (polyvinyl chloride), which is derived from vinyl chloride, it is clear that its properties make it suitable for various applications. PVC is a durable and resistant material, making it ideal for pipes, siding, and electrical cable insulation.
The polymer's resistance to chemicals and moisture, coupled with its relatively low production cost, underpins its widespread use in construction and plumbing. Furthermore, variations in the polymerization process can yield different types of PVC, which may exhibit varying flexibility and hardness. This versatility further emphasizes that the application of a polymer is indeed reliant on its intrinsic properties.
Step 3
Draw the structure of a polymer made from one of the above monomers.
Answer
The structure of polyvinyl chloride (PVC) can be represented as follows:
H H H H
| | | |
...C - C - C - C...
| | | |
Cl H Cl H
This illustrates the repeating unit of the polymer, where the vinyl chloride units are linked together, resulting in a long chain polymer.
