Abstract

POLìMEROS E SUA PREPARAçãO E USO COMO INIBIDORES DE HIDRATOS DE GáS. A presente invenção refere-se a polímeros com um peso molecular de média numérica de 500 a 500.000 glmol, que podem ser preparados por A) reação de um composto da fórmula (1) na qual n representa 0, 1 ou 2 e A representa um radical C~ 1~-C~ 40~ arbitrariamente substituído, com um composto da fórmula (lI) B(OH)~ m~, na qual m representa um número de 2 a 10 e B representa um radical C~ 2~-C~ 40~ arbitrariamente substituído, B) reação subseqúente do produto obtido desse modo com um ácido carboxílico que contém nitrogênio, que compreende 1 a 20 átomos de carbono, sendo que a relação molar entre o número dos grupos OH livres do poliéster obtido na etapa A e o ácido carboxílico que contém nitrogênio situa-se entre 1:0,1 e 1:1.
