Useful thermoplastic polymer powders are formed by a method comprising: cooling a foam comprised of a thermoplastic foam below the brittleness temperature of the thermoplastic polymer, wherein the foam has an average strut dimension of 10 to 500 micrometers, and comminuting the cooled foam to form a thermoplastic polymer powder. The method allows for the efficient grinding of the thermoplastic polymer having improved morphology and desirable characteristics such as dry flow without flow aids.
