How are polymers classified on the basis of structure?
Polymers are classified on the basis of structure as follows:
1. Linear polymers:
These polymers are formed of long straight chains. They can be
For e.g., high density polythene (HDP), polyvinyl chloride, etc.
2. Branched chain polymers:
These polymers are basically linear chain polymers with some
branches. These polymers are represented as:
For e.g., low density polythene (LDP), amylopectin, etc.
3. Cross-linked or Network polymers:
These polymers have many cross-linking bonds that give rise to a
network-like structure. These polymers contain bi-functional and
tri-functional monomers and strong covalent bonds between various
linear polymer chains. Examples of such polymers include bakelite
