Abstract
Both the shear viscosity eta(c) of dilute polymer solutions and Young's modulus Y(c) of nylon plus plasticizer with concentration c are assumed to be expressible as a power series in concentration. Scaling arguments are then presented which reveal an intimate relation between the coefficients of O(c) and O(c(2)) terms in both eta(c) and Y(c). The coefficient of the O(c(2)) term is predicted always to be positive, while that of the O(c) term can in principle have either sign. Comparison with experiment is made for eta(c) and Y(c). Some further experiments are proposed for both Y(c) and eta(c).
