<P>PROBLEM TO BE SOLVED: To provide a hyperbranched polymer suitable as a polymer material for nanofabrication, in particular, photolithography, and to provide a hyperbranched polymer having an acid decomposition group at the end of a molecule of the hyperbranched polymer obtained by a living radical polymerization reaction of a styrene derivative. <P>SOLUTION: The hyperbranched polymer has a core portion prepared by a living radical polymerization of chloromethyl styrene or the like, and an acid decomposition group such as p-tert-butoxy styrene, which is linked to the core portion and present at the end of a molecule of the polymer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
