Abstract
A multi-component ionomer, wherein, in a multi-component copolymer (D) comprising, as essential constitutional units, a structural unit (A) derived from at least one selected from the group consisting of ethylene and an α-olefin containing 3 to 20 carbon atoms, a structural unit (B) derived from a monomer containing at least one selected from the group consisting of a carboxy group and a dicarboxylic anhydride group, and a structural unit (C) derived from a specific acyclic monomer, at least a part of at least one selected from the group consisting of a carboxy group and a dicarboxylic anhydride group of the structural unit (B) is converted into a specific metal-containing carboxylate, and wherein a phase angle δ at which an absolute value G* of a complex modulus measured with a rotational rheometer is 0.1 MPa (G*=0.1 MPa) is from 50 degrees to 75 degrees.
