“…While −1 for CTPC in tetrahydrofuran (THF), acetone, dioxane, and pyridine at the temperatures T of 20 or 25 C was reported to be in a rather narrow range from 19 to 27 nm, the parameter in benzophenone, cycohexanol, and anisol was much smaller, that is, 7 -10 nm at relatively high temperatures (73 -94 C). Even though we consider the known temperature dependence of CTPC in four different solvents, that is, d ln −1 / dT ~ −6.5 10 −3 K −1 [13,22], the chain stiffness in the latter three solvents was found to be smaller than those in the former solvents. The solvent dependent conformation suggests that the intramolecular hydrogen bonding interactions and/or polymer-solvent interactions play an important role to determine the conformation of CTPC in dilute solution as pointed out by Sutter et al [9].…”
