Provided is a method for analyzing the dynamic state of a single polymer chain using a high-speed atomic force microscope or an atomic force microscope in order to clarify the structure-property relationship of a polymer material, and the like. Also provided are a manufacturing method for a polymer using this dynamic analysis method, a polymer manufactured by this manufacturing method, a manufacturing method for a synthetic polymer using this dynamic analysis method, and a synthetic polymer manufactured by this manufacturing method. This dynamic analysis method for a single polymer chain is provided with: a step for acquiring a dynamic image of the single polymer chain; a step for selecting an arbitrarily defined image among static images constituting the dynamic image; a step for numbering a plurality of portions of the single polymer chain using the selected static image; a step for performing displacement measurement of the numbered portions for each of the static images; and a step for, on the basis of th
