Abstract: The invention relates to foamed acrylic materials using both traditional chemical blowing agents as well as foamable microspheres. The acrylic foams have improved density reduction, optical properties, and insulation properties. The acrylic foams of the invention can be formed by traditional melt processing methods (extrusion, blow molding, etc.) as well as innovative foaming methods, such as foaming during or after polymerization.
