摘要：
The second virial coefficients of ring-shaped polystyrene in cyelohexane were determined at different temperature using low angle laser light scattering photometer (LALLS). The temperature obtained at which the second virial coefficient equals zero is 30 degrees C.That is the theta temperature of ring-shaped polystyrene in cyciohexane solution. It is 4.5 degrees C lower than that of linear polystyrene (34.5 degrees C). The Mark-Houwink equation of ringshaped polystyrene in cyclohexane at 30 degrees C and 35 degrees C were determined. They are [eta]=5.10 x 10(-2)M(W)(0.508), cm(3) g(-1) [eta] = 2.70 x 10(-2) M-W(0.576), cm(3) g(-1) respectively.
