Process for producing extruded foam with co2 as a blowing agent |
| abstract |
In one embodiment, the present invention relates to a process for preparing a foam product involving the steps of (A) forming a foamable mixture of (1) a polymer comprising about 10 % to about 90 % monomers of at least one of meta-substituted styrene and para-substituted styrene and 0 % to about 90 % monomers of styrene, and (2) a blowing agent containing a major amount of carbon dioxide under a pressure sufficient to prevent prefoaming of the mixture and (B) foaming the mixture into a region of reduced pressure to form the foam product. |
