Question

Which of the following is not used as a parameter for the classification of polymers?

• A. Source of polymer
• B. Structure of polymer chain
• C. Mode of polymerization
• D. Boiling point of monomer

Hint:

Common bases for classification of polymers:
• Source of polymer
• Structure of polymer chain
• Mode of polymerization
• Molecular forces (thermoplastics, thermosetting polymers, elastomers, fibres) Physical properties like boiling point or melting point of monomers are not used for polymer classification.

Answer 1

The Correct Option is D

To classify polymers, several parameters are considered, each representing a distinct physical or chemical characteristic of the polymer. Let's evaluate the options provided to identify which one is not typically used for classification:

1. Source of Polymer: Polymers are often classified based on their source, such as natural, synthetic, or semi-synthetic. This parameter helps in identifying the origin of the polymer material.
2. Structure of Polymer Chain: The structural arrangement of polymer chains plays a crucial role in their classification. Polymers can have linear, branched, or cross-linked structures, influencing their properties and applications.
3. Mode of Polymerization: The process by which polymers are formed also serves as a classification parameter. This includes addition and condensation polymerization modes, which impact the polymer's composition and characteristics.
4. Boiling Point of Monomer: The boiling point of the monomer is more related to the properties of the monomer itself rather than the polymer. It is not used as a standard classification criterion for polymers as it does not provide information about the polymer's structure, source, or formation process.

Given this analysis, the boiling point of monomer is not used as a parameter for the classification of polymers. Instead, the focus is usually on the characteristics related to the polymer as a macromolecule, not the properties of its monomers.
