Patent

CA 2613693

This disclosure is generally directed to a batch process of producing semi-- conductive polymer nanodispersions in which a composition comprising a liquid and a polymer is at least partially dissolved in the liquid, resulting in dissolved polymer molecules in the composition, wherein the dissolution occurs in a dissolution vessel. The solubility of the dissolved polymer molecules in the composition is then increased to increase the concentration of dissolved polymer in the composition to a range from about 0.1% to about 30% based on a total weight of the polymer and the liquid, wherein increasing the solubility of the dissolved polymer in the composition occurs in a dissolution vessel. The dissolved polymer in the composition is then diluted with a diluent, wherein the dissolution of the dissolved polymer in the composition occurs by addition of the composition to the diluent in a precipitation vessel.
