Patent

CA 2229548

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 wt % aqueous solution still has a Brookefield 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 plastics surfaces with non-slip protection.

L'invention concerne une composition contenant du polyacrylamide, qui se caractérise en ce que sa masse moléculaire est comprise entre 2.000 et 8.000 g/mol, déterminée par chromatographie par perméation sur gel (GPC) et qu'au titre de solution aqueuse à 15 % en poids, elle conserve même à 25 ·C une viscosité de Brookefield comprise entre 100 et 500 mPas. L'invention concerne en outre l'utilisation d'une composition de ce type contenant du polyacrylamide pour le collage en nappe de surfaces hydrophiles et dures, ainsi que pour rendre des surfaces plastiques antidérapantes.
