Module Overview
this is an overviewLearning Outcomes
- Represent the structure of a polymer using the model of a collection of strings
- Apply the string model of polymer structure to explain strengthening of polymers
- Critize the shortcomings of the string model of polymer structure as applied to the optical properties of polymers
- Explain the mer unit as the logical building block for understanding polymer structure
- Use molecular weight as a means of describing the average length of polymer molecules
- Differentiate between and infer the property implications of the following microstructural features of polymers: crystallinity, chain length, extent of cross-linking
- Recognize the mechanistic similarities between melting, plastic deformation, and chemical dissolution of polymers
- Show how differences in electronegativity between atoms in a molecule can create electric dipoles, which in turn can allow secondary bonding
