Process for producing hard acrylic and/or methacrylic polymer foams without using fluorocarbons as foaming agents |
| abstract |
In a process for producing hard acrylic and/or methacrylic polymer foams by polymerization and foaming of compounds of acrylic acid and/or methacrylic acid at high temperatures, an oligomer mixture, a flame-proofing agent and a nitrogen-splitting catalyst, a cell regulator, a foam stabilizer or foam regulator, a crosslinking agent and a wetting agent are polymerized and formed in a mold for 20 to 60 minutes. |
