摘要:
The invention provides for the use of copolymers comprising 1 to 99 mol % of structural units of the formula (1) in which R1 is hydrogen or C1-C6-alkyl, A is C2-C4-alkylene groups and B is C2-C4-alkylene groups, with the proviso that A is different than B, and x, y are each independently an integer of 1-100, and 1 to 99 mol % of structural units of the formula (3) in which R6 is hydrogen or C1-C6-alkyl, D is C2-C4-alkylene groups and z is an integer of 1-50, in amounts of 0.01 to 2% by weight, based on the water phase, as gas hydrate inhibitors.
