Abstract:
1. A method for preparing a carrier latex resin comprising: a) mixing at least one first anionic surfactant in a mixing vessel; b) combining at least one second anionic surfactant and, at least one aliphatic cycloacrylate and at least one dialkylaminoacrylate to form a mixture; c) transferring a portion of the mixture to the mixing vessel to form a carrier latex seed; d) optionally, adding an initiator to the carrier latex seed; and e) mixing the remaining portion of the mixture in the mixing vessel to form an emulsion comprising carrier latex particles; wherein said emulsion comprises a ζ potential less than about −55 mV and; said carrier latex particles are greater than about 85 nm in size; and wherein transferring the remaining portion of the mixture into the mixing vessel of step e) increases surfactant loading without impacting latex resin size as compared to a latex resin prepared in the absence of partitioning of surfactant.
