Description
本発明は、粒子の分散性に優れた新規なポリアルキレンイミン誘導体およびその用途に関する。 The present invention relates to novel polyalkylene imine derived body AND ITS applications excellent in dispersibility of the particles.
そこで、本発明が解決しようとする課題は、粒子を効率よく分散することができ、例えば洗浄剤や水処理剤等の用途において優れた性能を発揮しうる新規なポリアルキレンイミン誘導体およびその用途を提供することにある。 Therefore, an object of the present invention is to provide, can be well dispersed particles effectively, for example, novel polyalkylene imine derived material can exhibit excellent performance in applications such as detergents and water treatment agent AND ITS To provide a use.
本発明者は、上記課題を解決するべく鋭意検討を行った。その結果、分子量が粒子の分散性に大きく影響すると考え、（重量平均分子量−数平均分子量）／（重量平均分子量＋数平均分子量）という新たなファクターを案出し、この値が特定以下であると格段に粒子の分散性能が向上することを見出し、本発明を完成した。
すなわち、本発明にかかるポリアルキレンイミン誘導体は、ポリアルキレンイミン鎖に不飽和カルボン酸が付加したポリアルキレンイミン誘導体であって、（重量平均分子量−数平均分子量）／（重量平均分子量＋数平均分子量）の値が０．２７以下であり、ポリアルキレンイミンと不飽和カルボン酸とを反応させてポリアルキレンイミン誘導体を得るにあたり、前記ポリアルキレンイミンとして、（重量平均分子量−数平均分子量）／（重量平均分子量＋数平均分子量）の値が０．２６以下であるポリアルキレンイミンが用いられている、ことを特徴とする。
The present inventor has intensively studied to solve the above problems. As a result, the molecular weight is considered to greatly affect the dispersibility of the particles, and a new factor of (weight average molecular weight−number average molecular weight) / (weight average molecular weight + number average molecular weight) is devised, and this value is below a specific value. The inventors have found that the dispersion performance of particles is remarkably improved and have completed the present invention.
That is, the polyalkyleneimine derivative according to the present invention is a polyalkyleneimine derivative in which an unsaturated carboxylic acid is added to a polyalkyleneimine chain, and (weight average molecular weight−number average molecular weight) / (weight average molecular weight + number average molecular weight). value of) the Ri der 0.27, by reacting a polyalkyleneimine with an unsaturated carboxylic acid in obtaining the polyalkyleneimine derivatives as the polyalkyleneimine, (weight average molecular weight - number average molecular weight) / ( A polyalkyleneimine having a value of (weight average molecular weight + number average molecular weight) of 0.26 or less is used .

Hereinafter, described in detail for such polyalkylene imine derived body AND ITS application in the present invention, the scope of the present invention should not be restricted to these descriptions, even with the addition to the following examples, contrary to the object of the present invention Changes can be made as appropriate without departing from the scope. Hereinafter, the production method for obtaining the polyalkyleneimine derivative of the present invention may be referred to as “the production method of the polyalkyleneimine derivative of the present invention” or “the production method of the present invention”.
[Polyalkyleneimine derivatives]
The polyalkyleneimine derivative of the present invention is obtained by adding an unsaturated carboxylic acid to a polyalkyleneimine chain. The polyalkyleneimine derivative of the present invention can be easily obtained by the production method of the polyalkyleneimine derivative of the present invention described later, but is limited to those obtained by the production method of the present invention. is not. For example, instead of the method of adding an unsaturated carboxylic acid to a polyalkyleneimine by Michael, a method of adding an unsaturated carboxylic acid ester, amide, nitrile or the like to a polyalkyleneimine, followed by hydrolysis, etc. In addition, the polyalkyleneimine derivative of the present invention can be obtained.
