ABSTRACT:
Polymer particles having a hydrophobic core and various surface functional groups, particularly hydrophilic and chiral surface functional groups, are produced by adding a non-emulsified functional polymerizable monomer to the aqueous phase of a dispersion of soluble polymer particles which have previously been swollen with an emulsified-monomer and polymerizing the monomers. Preferably the particles are uniform macroporous beads.
