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).
