The redox polymerization of pyrrole, with ferric chloride as oxidant,
carried out in the presence of polyvinylpyrrolidone (PVP), yielded pol
ypyrrole latex particles. The polypyrrole latex was used, as seed, for
the radical polymerization of acrolein. The resulting polypyrrole cor
e/polyacrolein shell latex (poly(P/A)) was suitable for immobilization
of up to 11 mg of human serum albumin (HSA) and/or 33 mg of human gam
ma globulin (gamma G) per Ig of latex particles.
