METHOD FOR PRODUCING POLYAMIDES |
摘要 |
The invention relates to a method for producing polyamides by polymerization of lactams in the presence of metal oxides as heterogeneous catalysts. According to the invention, the metal oxides are placed inside a mold which permits mechanical separation from the reaction mixture and are removed from the reaction mixture during or after completion of the polymerization.
