<p>1. Large surface area systems with reactive units for bonding substrates containing nucleophilic groups, characterised in that the reactive units for bonding the substrates containing the nucleophilic groups are, from the nature of the manufacture, part of a polymer latex prepared by emulsion polymerisation which is made up of latex particles measuring from 0.03 to 6 mu m and the polymer latex itself is aggregated to form a large surface area system and/or is fixed to a carrier material with a large surface area.</p> |
