WebNov 12, 2013 · While the original Flory theory describes the size at a fixed temperature, as the number of monomers increases, it is possible to go beyond power laws in the current framework. The analysis allows one to discuss the temperature dependence of the size at a fixed number of monomers (assumed to be sufficiently large). WebThe Flory–Stockmayer theory was the first theory investigating percolation processes. [2] The history of the percolation model as we know it has its root in the coal industry. Since the industrial revolution, the economical importance of this source of energy fostered many scientific studies to understand its composition and optimize its use.
