Viscosity and Chemical Structure of Polymers

Abstract

A technique is described which has been found useful for understanding the role played by molecular structure in the viscosity of liquid polyisobutylene polymers. A linear logarithmic relation, between the viscosity and the average molecular weight of low molecular weight polyisobutylenes, is demonstrated. This relationship is used to indicate an apparent difference in the molecular structures of some polyisobutylenes.

A linear relation also exists between the molar refraction and a viscosity-constitutional constant in several homologous series of polymers which is useful for classification purposes.
