The above-mentioned initiator method and termination method are effective for synthesizing styryl-type macromonomers, but they are of acrylic type or methacrylic type (these are collectively referred to simply as acrylic type). When a compound of (1) is used as a polymerization initiator, the growth reaction is slow with an acrylic type initiator, and the carbon-carbon double bond of the initiator gradually decreases during the reaction. However, an acrylic macromonomer having a polyethyleneimine derivative chain could not be synthesized. Therefore, the present inventor conducted research for the purpose of providing an acrylic macromonomer expected to have a polymerization activity different from that of a styryl type, and as a result, produced an acrylic macromonomer having a novel polyethyleneimine derivative chain. Succeeded in doing
Furthermore, it has come to be possible to provide a novel graft polymer having a unique functionality and capable of various applications by using such a novel macromonomer.

It can be obtained by graft-polymerizing an acrylic macromonomer having a derivative chain. In copolymerizing the acrylic macromonomer having a polyethyleneimine derivative chain with the above-mentioned comonomer, a solvent is optionally used in a mixture of these monomers, and a radical polymerization initiator or an anionic polymerization initiator is added.

It was 0,1720. 1.2 mg of the copolymer obtained in Example 2 and 100.9 mg of polymethylmethacrylate having a molecular weight of 14,000 were dissolved in 1.9 ml of chloroform, cast on a glass plate, and allowed to stand at room temperature for 36 hours. And gradually dried to obtain a cast film. The thus obtained N-acetylethyleneimine chain content of 0.31% by weight was used to drop water droplets on the glass side and the air side of the film, and the contact angle of water was measured using a contact angle measuring device manufactured by Kyowa Interface Science Measured. The average value of 30 measurements each has a contact angle of 7 on the air surface side.
The contact angle on the glass surface side was 51 ° while it was 4 °. From this, it is understood that the hydrophilic N-acetylethyleneimine graft chain is localized on the glass surface side having a large surface free energy during the film formation, and as a result, the wettability to water is increased.
