A new polymer follows the Kelvin model. The quantity obeys the WLF equation, and E obeys rubber elasticity theory. The glass transition temperature of the polymer is 5C, where it has a viscosity of 1 x 10¹³ poises. The concentration of active chain segments is 1 x 10^-4 mol/cm³. The temperature of the experiment is 30C. How does this polymer creep with time under a stress of 1 x 10 ⁷ dynes/cm²? A plot of strain versus time is required.
