<p>The invention relates to the use of polymers which contain between 1 and 99 mol-% structural units of formula 1, wherein R<SUP>1 </SUP>represents hydrogen or C<SUB>1</SUB>-C<SUB>6 </SUB>alkyl, R<SUP>2 </SUP>represents C<SUB>1</SUB>-C<SUB>24</SUB>-alkyl, C<SUB>2</SUB>-C<SUB>24</SUB>-alkylene or a C<SUB>6</SUB>-C<SUB>18</SUB>-aryl radical, which can be substituted with a C<SUB>1</SUB>-C<SUB>12</SUB>-alkyl group, A represents identical or different C<SUB>2</SUB>-C<SUB>4 </SUB>alkylene radicals and, x, represents whole number from 2-40 in quantities from 0.01-2 wt-%, in quantities from 0.01 to 2 wt-%, in relation to the aqueous phase. The polymers can be used as gas hydrate inhibitors.</p> |
