MULTILAYERED STRUCTURAL POLYMER AND RESIN COMPOSITION CONTAINING THE SAME, ACRYLIC RESIN FILM-LIKE ARTICLE, ACRYLIC RESIN LAMINATION FILM, OPTICALLY THERMOSETTING RESIN FILM OR SHEET, LAMINATION FILM OR SHEET, AND LAMINATED FORMED PRODUCT BY LAMINATING THEM

摘要

PROBLEM TO BE SOLVED: To obtain a multilayered structural polymer suitable for obtaining an acrylic resin film-like article giving a molded article generating no whitening when it is insert molded or in-mold molded and having surface hardness, heat resistance, chemical resistance and transparency or matting properties sufficient to be used for vehicle application, and a resin composition containing the same. SOLUTION: In the multilayered structural polymer(I), (1) an innermost layer polymer (I-A) comprising an acrylic acid ester unit as a main ingredient, (2) an intermediate layer polymer (I-B) having 25-100°C glass transition temperature and different from the innermost layer polymer (I-A) and (3) an outermost layer polymer (I-C) comprising a methacrylic acid ester unit as a main ingredient are laminated in this order.
