A process for the preparation of a highly cohesive, non-thermoplastic elastomer-based pressure-sensitive adhesive is presented in which neither a solvent nor thermoplastic additives are used and yet thermal degradation during compounding is kept low. This is achieved by adding a vaporizable process agent, which is introduced into the adhesive after premixing of the constituents and evaporates abruptly there, whereby the adhesive is quenched. Furthermore, the use of water for cooling the adhesive is proposed and the highly cohesive PSA produced in this way and a pressure-sensitive adhesive tape with such an adhesive are presented. |
