The present invention relates to a foam containing a coupled propylene polymer and having a density in the range of from 9.6 to 801 kg/m<3> and having either a foamability factor of more than 1.8 to less than 2.8 and an open cell content less than 20 percent, or a foamability factor of equal to or more than 2.8 and less than 15 and an open cell content of less than 50 percent. The invention includes a process for preparing a foam including heating a coupled propylene polymer having a melt flow rate from 0.2 to 20g/10 min and a melt strength of a least 39 cN, optionally mixed with a nucleating agent, to a molten state to produce a molten polymer material, and mixing said molten polymer material with a blowing agent under conditions to produce a foamed material having a density in the range of from 9.6 to 801 kg/m<3>. The invention also relates to an article containing a foam containing a foam of the present invention.
