Abstract: An improvement in the process for producing foamed polyamide materials by anionically polymerizing lactam monomers wherein the foam produced has uniform cell size and improved properties is disclosed. The improvement comprises adding at least one foam stabilizing agent and at least one finely divided, porous substance to the monomers prior to polymerization.
