Copolymers useful for gelling acids |
| abstract |
Disclosed is a copolymer useful for preparing acid gels comprising a copolym er having a copolymer backbone, the copolymer having a general formula (I): wherein: (a) A is an H or other terminating group; (b) R1 is an OH or NH2; ( c) R2 is an O or NH; (d) Z is an integer having a value of from 1 to 4; (e) X a nd Y are present in a ratio (X:Y) of from 3:2 to 4:1; (f) structures I and II a re present as blocks or randomly distributed along the copolymer backbone; and wherein the copolymer has a molecular weight of from about 1,000,000 to abou t 10,000,000. |
