摘要：

A viscometric approach to the formation of interpolymer complexes between a polyelectrolyte, polyacrylic acid, and a non-ionic polymer, polyacrylamide, is investigated. The following method compares the reduced viscosity of the polymer mixture with an "ideal" value which results from the additivity of the reduced viscosities of the two components taking into account the polyelectrolyte effect of polyacrylic acid. This reveals the formation of a compact complex or gel-like interpolymer association which depends on the polymer mixture composition. Both the influence of the degree of polyacrylic acid neutralization and of the presence of a salt on the interpolymer association are also studied.
