A self-supporting and self-adhesive molded article is described having a glass transition temperature of less than 10&deg; C. and containing a binder and an aliphatic or cyoaliphatic nonionic surfactant. The binder may contain at least one addition polymer or addition copolymer. The article is redetachable from the material surfaces to which it may be adhered. Thus, the article may be attached, detached and reattached to a wall or cabinet surface and may have paper or other light weight, decorative material attached, detached and reattached to it. The detachment and reattachment process maybe repeated numerous times, particularly with intervening cleaning of the surface of the self-supporting and self-adhesive molded article.

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&deg; 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.
