| 中文摘要 | the glass transition temperature (t(g)) of cyclic polystyrene was measured by differential scanning calorimetry. there was a marked difference in the glass transition behaviour between cyclic and linear polystyrene. in the low molecular weight region (m(n) < 5 x 10(3)), the t(g) of the cyclic polystyrene increased with decreasing m(n), contrary to that of linear polystyrene. with m(n) higher than 5 x 10(3), the t(g) of cyclic polystyrene increased with increasing m(n). the t(g) of cyclic and linear polystyrene approached the same constant value when the m(n) was high enough (m(n) > 10(5)). combining the results of specific volume, it is believed that the variation of t(g) with molecular weight does not depend only on free volume effects but that configurational entropy is also an important factor. |
