PROCESS FOR PREPARING A POLY(P-METHYLSTYRENE) FOAM |
摘要 |
A process for preparing a poly(p-methylstyrene) polymer foam including extruding a poly(p-methylstyrene) foam structure from a melt at a temperature which will yield an open cell percentage less than that formed in general purpose polystyrene foamed under the same general conditions. It also includes performing the extrusion from a melt at a rate which will yield a foam structure at least comparable to that of general purpose polystyrene foam, wherein the extrusion rate is greater than the extrusion rate for said polystyrene foam. |
