Abstract

It is shown that the increase of the sample strength accompanying the charge of flocculant is conditioned by the growth of viscoelastic properties. The nature of the deformed paper in the presence of polyacrylamide in the composition both at pH5 and pH9 is determined by the processes taking place at the final stage of delayed-elastic deformations, as well as by the crack resistance at the last deformation stage.
