| titleOfInvention | Manufacturing method of (meth) acrylic polymer |
| abstract | In the conventional living radical polymerization process that uses a transition metal complex catalyst, in order to allow polymerization to proceed to a high monomer conversion rate and thereby obtain a polymer having a narrow molecular weight distribution when a reducing agent is used together and the amount of transition metal atoms of the transition metal complex is set to 30 ppm or less, it has been necessary to use a multidentate amine in excess relative to the transition metal. In addition, a method has been disclosed which allows polymerization to proceed even when the amount of multidentate amine is small, by adding an amine as a reducing agent; however, the reaction velocity is slow and thus it is difficult to achieve a high monomer conversion rate. However, in a method for polymerizing a (meth)acrylic monomer by living radical polymerization in the presence of a transition metal complex catalyst, the combined use of a multidentate amine (A), a base (B) and a reducing agent (C) makes it possible to achieve a rapid polymerization reaction and high monomer conversion rate and obtain a polymer having a narrow molecular weight distribution when 5-30 ppm by weight of copper atoms and a mole amount of 7 mmol% or less of multidentate amine (A) are used, each based on the total amount of (meth)acrylic monomer introduced. |
