    • The invention relates to polymers with a mean molecular weight of between 500 and 500,000 g/mol that can be produced as follows: A) reaction of a compound of formula 1, in which n stands for 0, 1 or 2 and A for an arbitrarily substituted C1-C40 group with a compound of the formula 2 B(OH)m in which m is from 2 to 10 and B is a represents an arbitrarily substituted C2-C40 group, B) subsequently reaction of the product thus obtained with a nitrogen-containing carboxylic acid which comprises from 1 to 20 carbon atoms, where the molar ratio between the number of free OH groups of the polyester obtained in step A and the nitrogen-containing carboxylic acid is between 1:0.1 and 1:1. The polymers are used to inhibit gas hydrate formation.
    • 本发明涉及平均分子量为500至500,000g / mol的聚合物,其可以如下制备:A)式1化合物与其中n代表0,1或2的化合物反应,A任意地反应 取代的C 1 -C 40基团与式2 B(OH)m的化合物反应,其中m为2至10,B 是代表任意取代的C 2 -C 40基团,B)随后将由此获得的产物与含有1至20个碳的含氮羧酸反应 原子,其中在步骤A中获得的聚酯的游离OH基团与含氮羧酸之间的摩尔比在1:0.1至1:1之间。 聚合物用于抑制气体水合物的形成。
