Most polymers have a lot of possible conformations. One way of chacterizing the average conformation of the chain is by using the root-mean-square end-to-end distance. What is the end-to-end distance and why is it useful? In your explanation use the examples of a stiff, rigid polymer (like kevlar) and a flexible polymer (like PE).
