Thermodynamic and Conformational Properties of Polystyrene. II. Intrinsic Viscosity Studies on Dilute Solutions of Linear Polystyrenes

Berry, G. C.·1967·The Journal of Chemical Physics

Abstract

The results of an extensive study of the intrinsic viscosity [η] of a series of linear, homogeneous (anionically prepared) polystyrenes (1.9<10−4M<440) over a wide temperature interval (10°<T<110°C) in decalin and toluene are described. The data are discussed in relation to the interaction parameter z=B0(〈s2〉0/M)−3/2(1−Θ/T)M1/2 in which the constants B0, Θ, and 〈s2〉0/M have been determined from thermodynamic studies reported in Part I of this series. It is found that [η]/[η]0 is not a single-valued function of z except for M>∼106. Above this molecular weight the dependence of [η]/[η]0 on z is satisfactorily predicted by recent calculations of Fixman; [η]/[η]0 is not linear in z contrary to other recent suggestions. The failure of the data on lower molecular weight polymers to be a single-valued function of z is discussed in terms of partial draining effects.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
