Molecular Structure
Forces between molecules
- Longer molecules have stronger forces of attraction between them. This tends to lead to longer chain plastics being
- High melting points
- Stiffer
- Harder
- Stronger
- Longer molecules have stronger forces of attraction between them. This tends to lead to longer chain plastics being
Modifying Plastics
- By increasing the chain length
- Makes it stronger
- Packing more closely
- Make it stronger and more dense
- A crystalline polymer
- Crosslinking
- Makes it harder
- Plasticizing
- Make it softer and more flexible
- By increasing the chain length
Structures of Plastics
- Some plastics have strong intermolecular forces between each molecule, these have high melting points and can be stretched easily
- Some plastics have weak forces between each molecule, these have low melting points and are rigid
