Branched Polymer vs. Linear Polymer: Know the Difference
By Shumaila Saeed || Published on December 26, 2023
Branched polymers have a tree-like structure with multiple branches off the main chain, while linear polymers consist of long, continuous chains without branches.
Key Differences
Branched polymers are characterized by their tree-like structure with side chains branching off from the main chain, whereas linear polymers consist of single, unbranched chains.
