发明名称 ADDITIVE FOR INHIBITING THE FORMATION OF GAS HYDRATES
摘要 <p>The invention relates to the use of polymers which contain between 1 and 99 mol-% structural units of formula 1, wherein R&lt;SUP&gt;1 &lt;/SUP&gt;represents hydrogen or C&lt;SUB&gt;1&lt;/SUB&gt;-C&lt;SUB&gt;6 &lt;/SUB&gt;alkyl, R&lt;SUP&gt;2 &lt;/SUP&gt;represents C&lt;SUB&gt;1&lt;/SUB&gt;-C&lt;SUB&gt;24&lt;/SUB&gt;-alkyl, C&lt;SUB&gt;2&lt;/SUB&gt;-C&lt;SUB&gt;24&lt;/SUB&gt;-alkylene or a C&lt;SUB&gt;6&lt;/SUB&gt;-C&lt;SUB&gt;18&lt;/SUB&gt;-aryl radical, which can be substituted with a C&lt;SUB&gt;1&lt;/SUB&gt;-C&lt;SUB&gt;12&lt;/SUB&gt;-alkyl group, A represents identical or different C&lt;SUB&gt;2&lt;/SUB&gt;-C&lt;SUB&gt;4 &lt;/SUB&gt;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>
