WebNov 12, 2013 · Flory mean-field theory. For an interacting polymer, the partition function, from equation ( 3.10 ), can be written as. with Δ F =− kBT (ln Z − ln Z0) as the excess free energy due to interaction. For the excluded volume case of equation ( 3.5 ), this excess free energy is called the free energy of swelling. high gloss canvas nature

The classical theories of Carothers, Flory and Stockmayer 1-5 describe the conversion of growing polymers to insoluble gels which occurs through crosslinking. All three theories use a statistical approach and assume that polymers approach infinite size at the gel point, i.e. they become one gigantic molecule. WebF. S. Leutner.
