Classification of Polymers
Classification of Polymers:
Based on the Source of Availability:
- Natural Polymers are polymers that occur spontaneously in plants and animals. Examples include resins, starch, and rubber.
- Semi-Synthetic Polymers are a type of natural rubber that has been traded. This means that natural rubbers are chemically processed to clarify them as semi-synthetic. For instance, this subcategory involves cellulose acetate and cellulose nitrate.
- Synthetic Polymers are polymers that have been entirely created by humans. Synthetic polymers such as polythene, nylon 66, and synthetic rubber are commonly employed.
Based on the Structure of the Monomer Chain:
- Linear Polymers are devised of monomers in a long, straight chain. PVC with a linear structure is also a polymer.
- Branched Polymers are linear polymers with few branches in them. One of all examples is low-density polythene.
- Cross-linked or network polymer: Polymers with cross-linked links between them are termed cross-linked or network polymers. They're in general, made up of bi-functional or tri-functional monomers. This type of polymer involves bakelite and melamine.
Based on Polymerization:
- Addition Polymerization: For Example, Teflon, poly ethane, Polyvinyl chloride (PVC)
- Condensation Polymerization: Example, Perylene, Nylon -6, 6, polyesters.
