Polyalkylenimine-derived polymer, its production process and uses |
摘要 |
An object of the present invention is to provide a polyalkylenimine-derived polymer and its production process and uses, wherein the polyalkylenimine-derived polymer can efficiently disperse such as liquid (particularly, water-soluble) dirt and dyes and can exercise excellent performances in uses for such as detergents and water-treating agents. As a means of achieving this object, a polyalkylenimine-derived polymer according to the present invention is an addition product of a carboxyalkyl group to a polyalkylenimine chain and is in the range of 30,000 to 5,000,000 in weight-average molecular weight. In addition, a process according to the present invention for production of a polyalkylenimine-derived polymer comprises a step of causing a polyalkylenimine of 20,000 to 1,000,000 in weight-average molecular weight and an unsaturated carboxylic acid to react together wherein the reaction is carried out under conditions where its reaction concentration is in the range of from 5 weight % up to an X value (weight %) determined by the following equation: <??>X value (weight %) = 34 - (ratio (mol %) of unsaturated carboxylic acid (mols) to be caused to react relative to all amino groups (mols) of polyalkylenimine chain)/5.
