Patent ID: 7473806

Claim:
A modified chain aliphatic polyamine composition obtained by addition reaction of a chain aliphatic polyamine represented by the following formula (2): H 2 N—(CH 2 CH 2 NH) n —CH 2 CH 2 NH 2 (2) wherein “n” represents a number of 0 to 4, and an unsaturated hydrocarbon compound selected from the group consisting of styrene and divinylbenzene, which composition comprises a first modified chain aliphatic polyamine represented by the following formula (1): R1R2N—(CH 2 CH 2 NR3) n —CH 2 CH 2 NR4R5 (1) wherein each of substituents R1, R2, R3, R4 and R5 represents independently a hydrogen atom or an unsaturated hydrocarbon residue selected from the group consisting of styrene residue and divinylbenzene residue, one of R1, R2, R3, R4 and R5 is an unsaturated hydrocarbon residue selected from the group consisting of styrene residue and divinylbeuzene residue, and a second modified chain aliphatic polyamine represented by the following formula (1): R1R2N—(CH 2 CH 2 NR3) n —CH 2 CH 2 NR4R5 (1) wherein each of substituents R1, R2, R3, R4 and R5 represents independently a hydrogen atom or an unsaturated hydrocarbon residue selected from the group consisting of styrene residue and divinylbenzene residue, one of R1, R2, R3, R4 and R5 is an unsaturated hydrocarbon residue selected from the group consisting of styrene residue and divinylbenzene residue, and “n” represents a number of 1 to 4.
