PROCESS FOR PREPARING EXPANDED POLYETHERIMIDE FILMS |
| abstract |
The present invention relates to a process for preparing a polyetherimide foam film by thermal expansion of a polyetherimide film impregnated with a porogenic solvent, characterized in that said porogenic solvent consists of acetone and that said film is impregnated homogeneously at an impregnation rate ranging from 13.5 to 17% by weight of acetone relative to its total weight. |
