摘要: Methods for manufacturing a polymer dispersion, polymer dispersions, and their use are provided herein. The methods of manufacturing the polymer dispersion comprise the steps of providing a reaction mixture in an aqueous medium comprising a polymeric dispersant and a monomer composition comprising radically polymerizable monomers, and subjecting the monomer composition in the reaction mixture to a radical polymerization to synthesize a dispersed polymer so as to form the polymer dispersion, wherein the weight average molecular weight of the dispersed polymer is in a specified narrow range. These polymer dispersions are designated as water-in-water (w/w) polymer dispersions.

摘要: A winterized paraffin inhibitor, which is capable of being used for preventing the deposition of paraffins in hydrocarbon streams and capable of withstanding freezing or crystallization at freezing or sub-freezing temperatures, may be formed by adding an oxyalkylated branched aliphatic compound having 12 or more carbons to a high molecular weight aliphatic polymer paraffin inhibitor, the oxyalkylated branched aliphatic compound having 12 or more carbons being produced by the oxyalkylation of the branched aliphatic compound having 12 or more carbon atoms in which the branched aliphatic compound having 12 or more carbon atoms is grafted with a polyether via a ring-opening reaction, wherein the polyether is a polymer of ethylene oxide, propylene oxide, butylene oxide, and combinations thereof.

摘要: A preparation method of comb structure temperature/pH-responsive polycarboxylic acid adopts acrylic ester, temperature/pH-responsive monomer and other raw materials to obtain polycarboxylic acid via acrylate monomer self-polymerization, grafting with temperature/pH-responsive monomers and hydrolyzation. In other words, acrylate is used as the reaction monomer to polymerize polyacrylate with controllable molecular weight under the action of initiator and chain transfer agent, then the graft copolymers are copolymerized with temperature/pH-responsive monomers to obtain graft copolymers with acrylate polymers main chain and temperature/pH-responsive polymer side chains. Finally, the graft copolymer is hydrolyzed to obtain the comb structure temperature/pH-responsive polycarboxylic acid with polyacrylic acid main chain and temperature/pH-responsive monomer side chain.

摘要: A flow improver comprising a plurality of core-shell particles that can be formed by emulsion polymerization. The core of the core-shell particles can include a drag reducing polymer, while the shell of the particles can include repeat units of a hydrophobic compound and an amphiphilic compound. The flow improver can demonstrate increased pumping stability over conventionally prepared latex flow improvers.
