Determination of equation of state parameters of poly(dimethylsiloxane)-benzene system by intrinsic viscosity

The equation of state exchange energy ( X 12) and entropy ( Q 12) parameters and the ratio of contact sites ( S 2/ S 1) of the poly(dimethylsiloxane)-benzene system were determined using equation of state theory and intrinsic viscosity measurements. The values of X 12 and Q 12 parameters for S 2/ S...

Description
Summary:The equation of state exchange energy ( X 12) and entropy ( Q 12) parameters and the ratio of contact sites ( S 2/ S 1) of the poly(dimethylsiloxane)-benzene system were determined using equation of state theory and intrinsic viscosity measurements. The values of X 12 and Q 12 parameters for S 2/ S 1=0.67 are found to be 16.64 J cm −3 and −0.0394 J cm −3 K −1, respectively.
