Abstract:
1. A multi-branched polymer, comprising: a polyalkylene glycol chain; a residue of a compound having three or more active hydrogen atoms; and a polymer portion having a constitutional unit derived from a vinyl monomer component, one end of the polyalkylene glycol chain bonding to the residue, and a terminal oxygen atom of at least one of the other ends of the polyalkylene glycol chain bonding to a main chain end of the polymer portion directly or via an organic residue, wherein said multi-branched polymer is represented by the following formula (1): wherein X is a residue of the compound having three or more active hydrogen atoms; each AO is a C2-C18 oxyalkylene group, and the AOs may be the same as or different from each other; each Y
