We study rheological (viscose-thixotropic) properties of solutions of poly(meth)acrylate materials and strength properties of samples of finishing materials based on poly(meth)acrylates with high values of inclusion volume fraction of a filler. It is established that viscose-thixotropic properties of finishing materials depend on inclusion volume fractions of polymer and filler in a solution as well as on quality characteristics of a dissolvent. It is shown that varying quality of dissolvent as compared to polymer filler, we may control strength properties of finishing materials.
