<p>Disclosed is a polymer material having excellent processability and excellent antibacterial or bactericidal effect. Specifically disclosed is an antibacterial or bactericidal agent which is composed of a hyperbranched polymer containing a quaternary ammonium salt represented by Formula (1). [In Formula (1), R1 represents a hydrogen atom or a methyl group; R2, R3 and R4 independently represent a linear, branched or cyclic alkyl group having 1-20 carbon atoms; A1 represents a structure represented by Formula (2); and n represents the number of repeating units which is an integer of 2-100,000.] [In Formula (2), A2 represents a linear, branched or cyclic alkylene group having 1-30 carbon atoms; and Y1, Y2, Y3 or Y4 represents a hydrogen atom.]</p> |
