Abstract
The invention discloses a compound containing a cyclic group having a disulfide structure, wherein the compound is shown as a general formula (1). In the general formula (1), R1 is any one of H and alkyl with 1-10 carbon atoms; R2 is any one of alkylidene with 1-10 carbon atoms; A is -O- or -NH-; and X is the cyclic group having the disulfide structure shown as a general formula (2). In the general formula (2), R3 and R4 are separately selected from any one of H and alkyl with 1-3 carbon atoms respectively; R3 or R4 on any one of n carbon atoms on a loop is substituted by a bond connected with R2; and n is an integer of 3-10. The compound provided by the invention is particularly suitable for improving a polyacrylamide copolymerization functional monomer with high-temperature viscosity stability of a polyacrylamide aqueous solution for tertiary recovery.
