Improved urethanic polymerisation by use of chelating agent is used as catalyst or cocatalysts |
| abstract |
A process of urethanic polymerisation is disclosed, in which a chelating agent is used as catalyst or cocatalyst. Preferred chelating agents for such use include hydroxyethylethylenediaminetriacetic acid and its salts and 2-hydroxy-1,3- diaminepropylenetetraacetic acid and its salts. Other suitable chelating agents include alkali metal salts of nitrile triacetic acid, ethylenediamine tetra- acetic acid, diethylene triamine-penta- acetic acid and N,N-di(2 - hydroxyethyl) glycine. |
