What is a polymer ?
|
A molecule of high molecular mass and are created of monomers.
|
|
|
What is the difference between a a high density polymer and a low density polymer ?
|
1. Low density- A shorter chain of monomers that are branched
2. High density- A longer chain of monomers that are less branched |
|
|
What is the relationship between order and crystallinity ?
|
The higher the amount of order, the higher the crystallinity.
|
|
|
Which factors does crystallinity influence ?
|
1. Melting Point
2. Density 3. Stiffness 4. Yield Stress |
|
|
What is cross linking and what effect will it have on a polymner ?
|
It is the process of chemically bonding polymer chains together using substances that will eventually strengthen a substance.
|
|
|
True or false: Vulcinisation is a process where short chains of a polymer are cross-linked.
|
True.
