One of the most accurate thermodynamic models describing them is the FJC model, and in that model, they can be thought of as various segments whose dimension is the Kuhn length. Another thermodynamic theory developed by Flory and Huggins describes their interactions in solvents. "Block" varieties of these are simply two or more different ones of these which are covalently bonded, and reactions in which these substances are produced from free radicals have initiation, propagation, and termination steps.  For 10 points, identify these substances which are composed of several building blocks, examples of which include polyethylene and polypropylene.
