Supramolecular polymers excluded volume

Chemically activated equilibrium polymerization of material in a good solvent was recently investigated by means of a scaling theory similar to that described for EPs [40], For this type of supramolecular polymer, the effect of excluded-volume interactions on the growth seems to be even more subtle than for EPs, and to be the most prominent very close to the polymerization transition. The location of the polymerization transition remains unaffected by the interactions but it becomes slightly more rounded because the initiator fraction r in Eq. (18) is replaced by yr 1.2r. For CAEPs the polymerization transition (at temperature Tp) and the crossover to the semidilute regime (at temperature T ) turn out to be quite close to each other, quite unlike the situation for EPs,...
