FIELD: chemistry of polymers, gluing materials.
SUBSTANCE: invention describes polymethyl(meth)acrylate-base polymeric gluing substance comprising the following components: (a) 1-10 wt.-% of silicic acid powder with the mean size of grains from 1 to 10 mcm (dull finishing agent), and (b) 1-10 wt.-% of silicic acid powder with the mean size of grains from 10 to 200 mcm (structural base) wherein the dull agent and the structural base comprise in common 11 wt.-%, not above, with respect to a polymeric gluing substance. By using the proposed substance in gluing the joint zone is not seen.
EFFECT: improved properties of substance.
