Patent ID: 8765008

Claim:
A hydroxyalkylated polyalkylene polyamine composition, comprising: at least two hydroxyalkylated polyalkylene polyamines represented by the following general formula (1): wherein R 1 to R 5 are independently a C 1 to C 3 alkyl group or a substituent represented by the following general formula (2): wherein R 6 and R 7 are independently a hydrogen atom or a C 1 to C 4 alkyl group, and p is an integer from 1 to 3, R 5 and R 1 , R 2 , R 3 , or R 4 may arbitrarily bond together to form a ring; at least one of R 1 to R 5 is a substituent represented by the general formula (2) but all of R 1 to R 5 cannot be substituents represented by the general formula (2) at the same time; n and m are independently an integer from 1 to 5; and a is an integer from 1 to 6, and the ratio of C 1 to C 3 alkyl groups to substituents represented by the general formula (2) among R 1 to R 5 in the general formula (1) is in the range of (C 1 to C 3 alkyl groups)/(substituents represented by the general formula (2))=70/30 to 30/70 (molar ratio).
