Abstract

Process for the preparation of polymer particles containing a vinylarene polymer by pre-polymerising vinylarene polymer, which pre-polymerised mass further contains an emulsifier, suspending the pre-polymerised mass; and polymerising vinylarene monomer in the suspended droplets. Further, the invention relates to polymer particles comprising vinylarene polymer, water and emulsifier, in which the amount of water ranges from more than 8 to 15 wt.%, based on total weight of the polymer particles.
