摘要:
A process which comprises mixing a carrier core with a polymer core and polymer shell and wherein the polymer shell is present as a coating on said core and said polymer core, wherein said polymer core is generated by emulsification of and heating of monomer forming a seed latex; adding a portion of said seed latex to said emulsification mixture, followed by heating and adding another second portion of said seed latex; and wherein said shell is generated by emulsion polymerization of a monomer, followed by heating.
