摘要：

A theory that describes the rheological properties of shear-thickening polymer solutions has been developed. This theory comprises an extension of Flory's theory of the expansion parameter to the case where macromolecules contain segments that can associate in an intramolecular fashion. Analysis of experimental results using this theory enabled determination of the association constant. It is then proposed that, when macromolecules with associating groups are placed in an elongational flow field of sufficiently high strain rate, they extend, thereby breaking intramolecular associations and allowing the formation of intermolecular associations, to an extent dictated by the association constant. The quantitative predictions of this theory are then compared with rheological measurements on a well known shear-thickening polymer, ICI's proprietary anti-misting kerosene additive, FM9.
