Stabilized extruded alkenyl aromatic polymer foams and processes for extruding stabilized alkenyl aromatic polymer foams

摘要

Prepare an extruded thermoplastic polymer foam having less 1000 parts per million, based on total polymer weight, of cations from water soluble salts that exist or form into a solid or glassy state that is less malleable than the thermoplastic polymer as the foamable composition exits an extrusion die during foam manufacturing using a brominated flame retardant, an innocuous stabilizer and a blowing agent containing water.
