This invention is related to a production method of anbranched polymern which comprises polymerizing a macromonomer [I], said macromonomer [I] being a vinyl polymer obtainablenby radical polymerization and terminally having onenpolymerizable carbon-carbon double bond-containing group pernmolecule. n Furthermore, by producing the macromonomer by livingnradical polymerization, in particular atom transfer radicalnpolymerization, it becomes possible to produce the abovenpolymers or gels having well controlled side chain molecularnweights.. |
