The persistence length describes these entities' stiffness, and their number-average degree can be found using the Carothers equation. They can be isotactic or syndiotactic and may be highly polydisperse. One of these molecules can be synthesized at the interface of two solutions in a "rope trick" reaction, first discovered by a DuPont researcher. They can be created in condensation or addition reactions by step-growth or chain-growth methods, respectively. Examples of these molecules include Kevlar, Teflon, PVC, and nylon. For 10 points, name these molecules composed of a chain of repeating monomers.
