ABSTRACT:
The present invention relates to a process for the preparation of porous polymer particles based on acrylate and/or methacrylate, comprising the steps of provision of a reaction mixture comprising at least one monomer chosen from the group consisting of acrylate and methacrylate compounds, and at least one monoterpene as porogen and of polymerization with the formation of porous polymer particles based on acrylate and/or methacrylate. The present invention also covers the porous polymer particles based on acrylate and/or methacrylate prepared in this way.
