Abstract:
We present a light scattering measurement of the correlation length for a series of critical solutions of polystyrene in methylcyclohexane with different molecular weights. Our results show that the correlation length ξ∼Nζνε−0.63, where N is the polymerization index and ε=(T−Tc)/Tc is the reduced temperature. The N exponent ζν is found to be 0.18±0.02, which is contrary to most earlier direct experimental results but in excellent agreement with theoretical predictions by de Gennes and Stepanow.
