ROLE OF THE STRUCTURAL-RHEOLOGICAL STATE OF POLY(METH)ACRYLATE SOLUTIONS IN THEIR SOAKING INTO CAPILLARY-POROUS BODIESD. N. Yemel'yanov, N. V. Volkova, O. I. Sheronova, and T. S. Krasil'nikova UDC 532.135:678.026.2:621.537.67 We have investigated the influence of the structural-rheological state of solutions of poly(meth)acryl copolymers on the rate of their capillary rise and the uniformity of the polymer distribution in the bulk of porous bodies - models of monuments of art made of ceramics, terracotta, loessial and lime plaster, and concrete. It has been found that in the region of concentrations corresponding to the transition of poly(meth)acrylate solutions from the viscous-Newtonian to the structural-viscous rheological state there is a sharp decrease in the rate of capillary rise of solutions into clay, chalk, and cement-sand specimens. A worsening of the uniformity of the polymer distribution over the height of the porous specimens, a decrease in their surface wetting with copolymer solutions, and a decrease in the value of the polymer adsorption on the filler surface are also observed.
