- Patent Document 3 discloses a method in which a nitroxide radical compound is reacted with a polymer in a solvent system and then a monomer is added to perform a graph reaction.
- the use of a radical initiator with a high hydrogen abstraction capability is essential for the first stage reaction in which a nitroxide radical compound is reacted with a polymer.
- a radical initiator since it is necessary to perform the reaction at a boiling point or lower of the solvent, it is necessary to use a radical initiator that cannot be reacted at a high temperature and decomposes at a relatively low temperature. It is an unstable compound and is dangerous and difficult to handle because it may be rapidly decomposed by temperature rise.
- Patent Document 3 uses a solvent in which all hydrogen is replaced with chlorine. However, these solvents have a high environmental impact. Yes. Furthermore, the reaction efficiency of the solvent system is lower than that of the non-solvent system, the introduction rate of the TEMP ° site in the first stage reaction is low, and the second stage graph starting from that site ⁇ Functional group introduction by reaction The problem is that the rate is also low.
