摘要：PURPOSE: To obtain an acrylic extrusion plate excellent in heating secondary moldability such as vacuum molding or pressure forming by using an acrylic polymer controlled in mol.wt. distribution. CONSTITUTION: An extrusion plate excellent in heating secondary moldability is formed by using an acrylic polymer based on a methylacrylate monomer unit and characterized by that a PMMA conversion wt. average mol.wt. measured by GPC is 7×10<4> -50×10<4> and a ratio of a PMMA conversion Z average mol.wt. and the PMMA conversion wt. average mol.wt. is 1.7 or more.
