A continuous method for making foams having uniform and/or small cell sizes and articles made with these foams are described. The method allows for adjusting or controlling cell size and cell size distribution by controlling temperature and/or blowing agent concentration. The foams feature small and/or uniform cell sizes and may be comprised of amorphous thermoplastic polymers, pressure sensitive adhesive compositions, and immiscible thermoplastic polymer compositions. A method for coextruding the foams is also described.
