SE DA A CONOCER UN COMPUESTO A BASE DE POLIACRILAMIDA, CARACTERIZADO POR TENER UN PESO MOLECULAR DE 2.000 A 8.000 G/MOL, DETERMINADO POR GPC, Y UNA VISCOSIDAD BROOKEFIELD RESIDUAL DE 100 A 500 MPAS COMO SOLUCION ACUOSA AL 15 % EN PESO A 25 SI COMO LA UTILIZACION DE UN COMPUESTO DE ESTE TIPO A BASE DE POLIACRILAMIDA PARA EL ENCOLADO DE SUPERFICIES HIDROABSORBENTES Y SUPERFICIES DURAS, Y PARA EL RECUBRIMIENTO ANTIDESLIZANTE DE SUPERFICIES DE MATERIAL PLASTICO. The invention concerns a polyacrylamide-containing composition which is characterized in that it has a molecular weight of between 2,000 and 8,000 g/mol, determined by means of gel permeation chromatography (GPC), and as a 15% aqueous solution still has a Brookfield viscosity of between 100 and 500 mPas at 25° C. The invention further concerns the use of this polyacrylamide-containing composition for the flat bonding of water absorbent and hard surfaces and for equipping plastic surfaces with non-slip protection.
