Abstract

See full text

Provided is a process for reducing the size of ethylcellulose polymer particles comprising

    (a) providing a slurry comprising (i) water(ii) said ethylcellulose particles, wherein said ethylcellulose polymer particles have D50 of 100 μm or less;(iii) surfactant comprising 1.2% or more anionic surfactants by weight based on the solid weight of said slurry, with the proviso that if the amount of anionic surfactant is 2.5% or less by weight based on the solid weight of said slurry, then said surfactant further comprises 5% or more stabilizers by weight based on the solid weight of said slurry, wherein said stabilizer is selected from the group consisting of water-soluble polymers, water-soluble fatty alcohols, and mixtures thereof. (b) grinding said slurry in an agitated media mill having a collection of media particles having a median particle size of 550 μm or smaller.
