چکیده	In this work, styrene-methyl methacrylate (St/MMA) copolymer particles were synthesized by suspension polymerization process. The weight ratio of St to MMA is 53 to 47. The synthesized copolymer particles were impregnated by n-pentane and then particles expansion was recorded. The foams cell structure was studied by scanning electron microscopy (SEM). Different foaming conditions effect on the expansion behavior of copolymer was examined. It was concluded that sorption pressure and temperature have contradictory effects on the foaming ratio of the synthesized copolymers at lower and higher sorption pressures and the results were confirmed with the foams cell structure studies.
