The critical overlap concentration (C^*) and the critical entanglement concentration C_B^* of linear polystyrene (LPS) and branched polystyeene (BPS) have been disseussed. The values of C^* and C_E^* were calculated according to the Graessley and Klein equation C^*=0.77/[η], C^*=1.08/[η], respectively. The results showed that the C^* and C_E^* of branched polystyrene were larger than those of linear polystyrene.
