The invention relates to an acrylic formulation having an acrylic matrix and 1-20 percent by weight of a very high molecular weight acrylic processing aid, with a weight average molecular weight of greater than 5,000,000 Daltons. The formulation has a high melt strength, yet is processable under typical melt processing conditions. The formulation is useful for melt-processed products, including extruded products such as extruded sheet, foam, co-extruded profiles, blown films, and other objects typically formed by a heat processing operation. Useful acrylic matrices include Plexiglas® and Solarkote® resins from Arkema Inc. |
