Partial derivatives of the strain energy function t3W/Oll and O W/OI2 are widely evaluated for various rubber vlucanizates under small to very large extension. The Mooney-Rivlin plot is reproduced with the plot of the original equation, tr = 2(2- 2 -2) (OW/c~I1 + 2-~cgW/cgI 2 ), in which an inevitability for the plot to give a straight line is not found. Even if a straight line is obtained, the constants Ca and C2 differ from OW/cgI~ and 0W/c312, respectively.
