| titleOfInvention | Novel hydrophobically associating polymer and preparation method and application thereof |
| abstract | The invention relates to a novel hydrophobically associating polymer which comprises the following components: acrylamide, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid sodium salt, a hydrophobic monomer, a zwitterionic monomer, urea, a surfactant, a sodium hydroxide aqueous solution, deionized water, a chelating agent, a soluble azo initiator, a chain transfer agent, an oxidant and a reducing agent. Uniformly mixing acrylamide, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid sodium salt, a hydrophobic monomer, a zwitterionic monomer, urea, deionized water and a surfactant, and adjusting the pH value; cooling, filling nitrogen to remove oxygen, then respectively adding azo initiator, chelating agent, chain transfer agent, oxidant and reducing agent to initiate polymerization reaction, removing nitrogen after the solution temperature is obviously and rapidly raised to obtain polymer colloid, drying, pulverizing and sieving to obtain flocculant powder. The polymer solution has excellent temperature resistance and salt resistance, and is more beneficial to the oil displacement application field of the polymer. |
