Process for the production of a latex having a high solids content, with a low viscosity and a a bimodal distribution

摘要

The invention concerns a latex consisting of polymers dispersed in a bimodal distribution, having a non-volatile matter content at 55 % and low viscosity. Said latex is obtained by emulsion polymerisation of at least a monomer in the presence of a seed of polymer-based particles with a diameter ranging between 200 and 450 nm. The invention also concerns the use of said latex in various applications such as pressure sensitive adhesives, floor bonding adhesives, tile bonding adhesives, additives for mortar, sealants, sealing joints.
