ABSTRACT:
Disclosed is a process for making an extruded alkenyl aromatic polymer foam with a thickness of about 1 inch (2.54 cm) or more and having an enhanced cell size. From about 0.2 to about 2.0 percent by weight of a glycerol monoester of a C.sub.8-24 fatty acid is incorporated to increase cell size about 5 percent or more relative to a corresponding foam without the glycerol monoester. The blowing agent is about 50 percent or more of a blowing agent selected from the group consisting of carbon dioxide, 1,1,1,2-tetrafluoroethane, and 1,1,1-trifluoroethane. Further disclosed is an extruded alkenyl aromatic polymer foam obtainable from the process.
