Summary: A process for preparation of poly(acrylic acid) particles dispersed in oil is presented. The process comprises two steps: the first step involves the preparation of a poly(acrylic acid) solution, while the second step consists in the preparation of the polymer particles by dispersing the polymer solution in an organic phase. During the second step, modification of the polymer chain structure can be performed through chemical reactions. One of the advantages of the proposed process is the possibility to produce particles loaded with drugs or other chemical compounds. Besides that, if the continuous phase is vegetable oil, purification of the reaction medium may not be necessary.
