Influence of fluctuating networks on the structural-mechanical properties of diphilic copolymer solutions

Abstract

The fluctuating networks of an amorphous nature, arising in any polymer solution having a concentration near the inverse intrinsic viscosity [1], determine in many ways the structural-mechanical properties of the solutions. It is very difficult to separate their effect from that of other parameters because of the changes of all the other parameters when diluting the solution to the extent necessary to eliminate these networks. A direct observation of the amorphous networks by the available means is still more difficult, chiefly because of their fluctuating nature. Their modelling [2,3] by diphilic copolymer solutions, which give an opportunity of controlling the formation of the inter-chain hydrogen bonds, is a promising method, which makes possible a definite evaluation of the network effects on the structural-mechanical properties of solutions. © 1967.
