“…M , where M is the molecular weight in g/mol and [η] is the intrinsic viscosity in Pa•s, evaluating the linear slope between these variables, and converting this value into Kuhn length and diameter. 10,11,63,64 Kuhn lengths calculated with the Bohdanecky plot generally agree well with those determined from the Yamakawa−Fujii treatment but the rod diameters obtained with Bohdanecky theory tend to have stronger agreements with experimentally determined values. 11,63 Testing their theory on hydroxypropyl methylcellulose (HPMC), Bustamante, Navarro-Lupioń, and Escalera related the intrinsic viscosity to the solvent's Hansen solubility parameters (δ d,s , δ p,s , and δ h,s ) to estimate the solubility parameters of the polymer (δ d,p , δ p,p , and δ h,p ) through eq 4.…”
