Abstract: The present invention relates to a process for preparing open-cell microcellular polystyrene foam by adding suitable polyamide as nucleating agent into the process to produce polystyrene foam having microcellular open-cell. The process comprises the steps of blending polystyrene and a polyamide polymer to give a homogeneous mixture, adding a foaming agent into the mixture and blending to give a polymer foaming solution, and finally extruding and foaming the polymer foaming solution in an extruder. The present invention also relates to the open-cell microcellular polystyrene foam prepared by the process.
