| titleOfInvention | Acrylamide monomer and acrylamide copolymer, method of preparation, application and oil displacement agent |
| abstract | The invention relates to an acrylamide monomer and a preparation method, the method comprises the following steps: contacting 3-methyl-2-butylene, a sulfonating agent and acrylonitrile for 1-4 hours under -5-15 DEG C to obtain the acrylamide monomer in a formula (I). The invention also relates to the acrylamide copolymer, the preparation method and the application. The preparation method comprises the following steps: under the condition of a solution polymerization reaction, under the existence of an initiator, a monomer mixture is performed with polymerization, the monomer mixture contains acrylamide and a monomer C, the viscosity-average molecular weight of the obtained after polymerization is more than 30 million by the condition of the solution polymerization reaction. The acrylamide copolymer is capable of resisting high temperature, and has good viscosifying effect under high ore degree, can be widely used in petroleum chemical field, and can especially be a displacement agent for three-time oil extraction oil. (img file='DDA00002332890900011.TIF' wi='747' he='220' /) is formula (I). |
