This invention is related to a production method of a branched polymer
- which comprises polymerizing a macromonomer [I],
- said macromonomer [I] being a vinyl polymer obtainable by radical polymerization
and terminally having one polymerizable carbon—carbon double bond-containing
group per molecule. Furthermore, by producing the macromonomer by living radical
polymerization, in particular atom transfer radical polymerization, it becomes
possible to produce the above polymers or gels having well controlled side chain
molecular weights.
