THERMOSENSITIVE CYCLOTRIPHOSPHAZENE DERIVATIVES AND A PREPARATION METHOD THEREOF

摘要

The present invention relates to novel cyclotriphosphazene derivatives represented by Formula (1) and a preparation method thereof wherein HNA is an amino acid group selected from glycine group(-NHCH2COO<->), aminomalonic acid group(-NHCH(COO<->)2), aspartic acid group (-NHCH(CH2COO<->)COO<->) and glutamic acid group (-NHCH(CH2CH2COO<->)COO<->), m is a repeating unit of poly(alkoxyethyleneglycol) selected from 2, 7, 12 and 16, and n is an integer representing number of alkyl carbons and selected from 0, 1, and 3.
