NEW MATERIAL:The azoamide compound of formula (at least one of X 1 WX 3 is OH and the others are H). n EXAMPLE: 2,2'-Azobis[2-methyl-N-(1,1-dimethyl-2-hydroxyethyl)prop-ionamide]. n USE: A water-soluble radical-polymerization initiator. It has high activity, and is useful extremely for the radical polymerization at a relatively high temperature. It is expected to be effective to introduce hydroxyl group to the terminal of a polymer, convert the polymer to a reactive polymer, and give a polymer having excellent hydrophilic property, printability, antistatic property, etc. n PREPARATION: The compound of formula I can be prepared by reacting the azoester of formula II with the amine of formula III in the presence of a basic catalyst (e.g. sodium methoxide). n COPYRIGHT: (C)1986,JPO&Japio |
