<p>PROBLEM TO BE SOLVED: To provide an acrylic polymerized molded body capable of obtaining a foam molded body with high strength while suppressing disadvantages such as defective foaming, a method for manufacturing the acrylic polymerized molded body, and a foam molded body with high strength using the acrylic polymerized molded body.SOLUTION: An acrylic polymerized molded body contains a polymer having a constitution unit derived from methyl methacrylate and a constitutional unit derived from (meth)acrylic acid, and a chemical foaming agent, and has 35-59 points in hardness to be measured according to JIS K 6253:1997. A method for manufacturing an acrylic polymerized molded body includes heating and polymerizing a polymerizable solution containing methyl methacrylate, (meth)acrylic acid, and a chemical foaming agent at 35-49°C. A foamed molded body is obtained by subjecting the acrylic polymerized molded body to heat foaming.</p> |
