Q13. What is the structural difference between HDP and LDP? How does the structure account for different behaviour and nature, hence using a polymer?
Answer: HDP (High-Density Polymer) consists of a linear molecule and high density due to close packing. It is a translucent polymer. While LDP (Low-Density Polymer) has a highly branched structure and hence, does not pack well, resulting in low density. It is a transparent polymer.
