Initially, the emulsion homopolymerization of three different soft biobased methacrylates is investigated; 2-octyl methacrylate (OMA), tetrahydrogeraniol methacrylate (TGM) and tetradecyl methacrylate (TDM). The challenges to polymerize these monomers by emulsion polymerization are addressed and the properties of the homopolymers obtained measured (T_g and molar masses). Secondly, the three different soft biobased methacrylates are copolymerized by seeded semibatch emulsion polymerization with tetrahydrofurfuryl methacrylate (THFM) which is a hard and more hydrophilic biobased monomer.
