Abstract
Butanone was used as a theta solvent for poly(o-chlorostyrene) at 25°C as determined by the measurements of the precipitation temperatures of solutions. Based on lightscattering and viscosity measurements, the molecular weight dependencies of the intrinsic viscosity, the second virial coefficient and the end-to-end distance of the polymer were determined as follows: [η], 4.60×10−4 Mw0.50 (dl/g) in butanone, [η], 1.15×10−4 Mw0.66 in toluene; A2, 25.1×10−4 Mw−0.19 (mol·cc/g2) in toluene; ‹L2›1/2, 0.563×Mw0.50 (A) in butanone, ‹L2›1/2, 0.301×Mw0.58 in toluene. The Kθ value for the butanone solution is smaller than that previously obtained for the toluene solution with the aid of the Stockmayer–Fixman relation. This difference is considered to be the effect of the solvent on the polymer dimension.A viscosity plot of the Stockmayer–Fixman type in toluene solutions gives a downwards curvature instead of a straight line over the whole range of the polymer molecular weight.The σ value, 2.15, found from the unperturbed dimension of poly(o-chlorostyrene) in butanone is comparable to that of poly(p-chlorostyrene).
