<p>PROBLEM TO BE SOLVED: To provide a high-frequency-welded article excellent in softness, mechanical properties, and adhesion by high-frequency welding. SOLUTION: The objective article is prepared by subjecting an article prepared by melt mixing and molding multilayered polymer particles to high-frequency welding. The polymer particle has a rubber component layer (I) formed by copolymerizing a monomer mixture containing an acrylic ester and a polyfunctional monomer and a thermoplastic resin component layer (II) formed by copolymerizing a monomer mixture containing a methacrylic ester and another monomer and satisfies the following conditions: (1) the number average mol.wt. of the thermoplastic resin component constituting the outermost layer is 30,000 or lower; (2) the mass ratio of layer (I) to layer (II) is (30/70)-(90/10); and (3) the average particle size is 150 nm or lower.</p> |
