ABSTRACT:
A process for producing structural aromatic polycarbonate thermoplastic foam is provided which involves gas expansion of a melted aromatic polycarbonate thermoplastic resin composition containing an amount of a polytetrafluoroethylene nucleating agent. The thermoplastic resin compositions provided exhibit an improved uniformity of cell structure in the resultant structural thermoplastic foam as a result of the incorporation of the polytetrafluoroethylene nucleating agent. The process and compositions are useful in the production of structural thermoplastic foam articles.
