Problems solved by technology

[0003] When the polyacrylamide compounds in the prior art are used at high temperature, the viscosity will drop too fast, or even the viscosity will be seriously lost, which cannot meet the needs of practical applications.
[0004] In this regard, those skilled in the art have also proposed a series of improvement measures, such as: hydrophobic association polyacrylamide is to directly introduce a certain number of hydrophobic side groups on the polyacrylamide main chain to achieve hydrophobic association, so as to achieve The purpose of resistance to temperature and salt; however, the water solubility of hydrophobic monomers is poor, and it is difficult to achieve copolymerization with acrylamide monomers, and complex polymerization implementation methods are required

Embodiment 1-4

[0080] A kind of preparation method of acrylic acid-acrylamide-allyl polyether copolymer, comprises the steps:

[0081] Take 40mL of deionized water and put it in a sealed bag, pour the weighed acrylic acid (AA) into the sealed bag and stir evenly, adjust the pH value to 7-8 with 0.1mol / L sodium hydroxide solution;

[0082] Add the weighed acrylamide (AM) and allyl polyether (APEG and APPG), stir evenly, and pass nitrogen for 30 minutes to fully discharge the oxygen in the container and the solution;

[0083] Add the weighed initiator, stir evenly, then put the sealing bag into the water bath after sealing, at T 1 react at temperature;

[0084] Then the water bath was heated to T 2 , continuous reaction, to obtain colloidal polymer;

[0085] After drying, crushing and sieving, an acrylic acid-acrylamide-allyl polyether copolymer is obtained.

[0086] The reaction raw material consumption of the embodiment of the present invention 1-4 is as shown in table 1

[0087]

Abstract

The invention provides an acrylic acid-acrylamide-allyl polyether copolymer and a preparation method thereof. The acrylic acid, acrylamide and allyl polyether with different molecular weights are used as raw materials to prepare the acrylic acid-acrylamide-allyl polyether copolymer. The viscosity reduction phenomenon of the obtained copolymer under a high-temperature condition can be effectively improved, the viscosity loss is reduced, and higher use requirements are met. The acrylic acid-acrylamide-allyl polyether copolymer is excellent in high temperature resistance, the viscosity reduction speed at high temperature is low and the viscosity loss is low.

Description

technical field [0001] The invention relates to the technical field of functional copolymers, in particular to an acrylic acid-acrylamide-allyl polyether copolymer and a preparation method thereof. Background technique [0002] Polyacrylamide compounds are a general term for acrylamide homopolymers or polymers copolymerized with other monomers, and are widely used in petroleum exploration, papermaking, water treatment, textiles, medicine, agriculture and other industries. [0003] When the polyacrylamide compounds in the prior art are used at high temperature, the viscosity will drop too fast, or even the viscosity will be seriously lost, which cannot meet the needs of practical applications. [0004] In this regard, those skilled in the art have also proposed a series of improvement measures, such as: hydrophobic association polyacrylamide is to directly introduce a certain number of hydrophobic side groups on the polyacrylamide main chain to achieve hydrophobic association...
