The successful use of multitasking polycaprolactone-based hydrophobins for miniemulsion polymerization of model monomers like styrene and methyl methacrylate is demonstrated. These hydrophobins were synthesized in two steps - the synthesis of polyester diol (i.e., polycaprolactone diol) followed by polycondensation with an equimolar amount of azobis(cyanopentanoic acid dichloride). The hydrophobin, besides acting as a hydrophobe and initiator for the miniemulsion polymerization, also provided functionality; in this case degradability to the miniemulsion. An optimum ratio of hydrophobin to monomer was required for making stable dispersions of a small size (average diameter around 100 nm) with relatively high solid content (around 22%).
