Patent Images
1. A process for making substantially uniform oligomeric droplets comprising:
- preparing an aqueous emulsion having an emulsifying agent that is not an anionic surfactant, at least one monomer, a chain transfer agent, and an initiator, wherein the initiator is selected from the group consisting of benzoyl peroxides, t-butyl peroctoates, t-amyl peroxypivalates, oil-soluble peroxides, oil-solubule azo compounds, and mixtures thereof; and
mixing the aqueous emulsion with at least a stabilizer that is not an anionic surfactant and a plurality of seed particles to grow an aqueous dispersion of oligomeric droplets, having a 90/10 uniformity coefficient of 1.0 to 1.3.
