| description | The inhibition or retardation of the formation, growth and/or agglomeration of hydrates in the body of a fluid comprising water and a gas, such as natural gas, petroleum or other gases comprises the incorporation of a water soluble homo- or co-polymer derived from a nitrogenous polymer which may be a cationic, amphoteric or neutral monomer chosen from: (i) a monomer (A) of general formula R'-C(CH2)-R''-R1-N-R2(R3) (I), where: R' = H or Me; R'' = -COO-, -CO-NH-, -CO-NH-CO-NH-, or -C6H4-; R1 = -(CH2)n, where n = 1-3, -C(CH3)2, -C(CH3)2-(CH2)2- or -CH2-CH(OH)-CH2; R2 = H, Me, Et or i-Pr; and R3 = H, Me or Et; (ii) a monomer (B) of general formula R'-C(CH2)-C(O)-NH-R4 (II), where: R' = H or Me; and R4 = -C(CH3)2-CH2-, CO-CH3 or -CH2OH; (iii) a monomer (C) of general formula (IIIa) or (IIIb), where: R1 = H or Me; (iv) a monomer (D) of formula (IV), where: R' = H or Me; and (v) a monomer (E) of general formula (CH2=CH-(CH2))2-NR5 (V), where: R5 = CnH2n+1, with n = 1-10, OH or (CH2)2-CO-NH2. |
