Abstract
Self-adhesive adhesives have been known since 1935. Since then, many categories of their division have been distinguished, depending on their origin, state of aggregation, operating conditions, obtaining, chemical base or binding mechanism, as well as many other properties. The main is their application in natural and synthetic adhesives, that is due to the origin of the high molecular weight compounds used for their production. The following work describes the types of water-soluble natural and synthetic adhesives. In recent centuries, there has been a decline in the use of natural polymers for the synthesis of water-soluble pressure sensitive adhesives. This is due to the spread of cheaper products from petrochemical resources, but also better properties that they characterize. For their polymerization, synthetic monomers which hydrophilic groups (hydroxyl, amide or carboxyl) are used. These groups, in the further reaction stage, after polymerisation, give the possibility of cross-linking of the pressure-sensitive adhesive. Polyacrylate based adhesives are among the most commonly used adhesives. It is forecasted that the demand for such adhesives will increase on average by 2.9% per annum. Dispersive, water-soluble, self-adhesive adhesives and those in which the solvent is water also play an increasingly important role. This happens as a result of legal requirements, but also greater public awareness of ecology.
