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(CH¿2?CH2COO?-)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.
