Source-Based Nomenclature
- Homopolymers.
- Copolymers.
- Non-linear polymers.
- Regular single-strand organic polymers.
- Regular double-strand organic polymers.
What is nomenclature rules?
The IUPAC nomenclature system is a set of logical rules devised and used by organic chemists to circumvent problems caused by arbitrary nomenclature. Knowing these rules and given a structural formula, one should be able to write a unique name for every distinct compound.
What are the classification of polymer?
There are 3 principal classes of polymers – thermoplastics, thermosets, and elastomers. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline.
