Webrings are a very critical feature: they permit molecular rotation of the various parts of the molecule. This flexibility in turn means that a polyphenyl ether can remain liquid at fairly low temperatures - an important characteristic for many lubricants. The pour point of a 5-ring polyphenyl ether, for example, is 4° C. (40° F.). http://www.chemassociates.com/products/findett/PPEs_LubEng.pdf
