Three-dimensional printing processes using 1,1-di-activated vinyl compounds

A process for producing an article by three-dimensional printing includes applying a 1,1-di-activated vinyl compound-containing liquid binder over a predetermined area of a layer of solid particles. The liquid binder infiltrates gaps between the solid particles to form a first cross-sectional layer of an article, and the 1,1-di-activated vinyl compound reacts to solidify the liquid binder and bind the solid particles in the first cross-sectional layer of the article. Also provided is an article produced by the three-dimensional printing process, set forth herein.

REMOVAL OF WATER-IN-CRUDE OIL EMULSIONS USING HYDROPHOBIC AND HYDROPHILIC ACRYLIC MACROMOLECULES

The present disclosure refers to the development of novel random bipolymers, which are comprised of alkyl acrylate and alkoxy alkyl acrylate monomers, as hydrophobic and hydrophilic components, respectively. These bipolymers are synthesized by means of semi-continuous emulsion polymerization, under strict conditions of monomer deficiency, to ensure the randomness and homogeneity of the chains. The application in dissolution of these random bipolymers has shown a dehydrating capacity superior to that of polyethers and phenolic resins, with the additional advantage of being soluble in crude oil. The random bipolymers show excellent performance as breakers of water-in-crude oil emulsions, coalescers of water droplets and clarifiers of the removed aqueous phase, and are chemically stable under acidic conditions.
