We describe, for the first time, the use of tailor-made reactive polymeric stabilizers for the synthesis of polypyrrole colloids. Using a poly(2-(dimethylamino)ethyl methacrylate-stat-3-vinylthiophene) stabilizer, the polypyrrole particles had diameters of approximately 100 nm, contained 19 wt % stabilizer, and exhibited solid-state conductivities as high as 4 S cm(-1).
