Chemical Engineering
Polymer Technology
Difficulty: Easy
Choose an option
-
AMicromolecules
-
BMacromolecules
-
CSub-micromolecules
-
DNone of these
Answer
Correct Answer: Macromolecules
Explanation
Introduction / Context:Terminology matters. “Polymer” literally means many parts; polymer chains are very large molecules composed of repeating units called monomers. The standard term “macromolecule” captures their high molecular mass and chain nature.
Given Data / Assumptions:
- We only need the accurate, widely accepted definition.
Concept / Approach:Macromolecules possess molecular weights ranging from thousands to millions, often with distributions (polydispersity). Their size and entanglement drive viscoelastic behaviour and processing responses (e.g., melt viscosity scaling strongly with molecular weight).
Step-by-Step Solution:Select “macromolecules.”
Final Answer:Macromolecules
