| 中文摘要 | the glass transition temperature (t-g) of mixtures of polystyrene (ps) with different molecular weight and of blends of poly(2,6-dimethyl-p-phenylene oxide) (ppo) and polystyrene with different molecular weight (dmwps) was studied by a dsc method. for the whole range of composition, the curves of t-g vs composition obtained by experiment were compared with predictions from the fox, gordon-taylor, couchman and lu-weiss, equations. it was found that the experimental results were not in agreement with those from the fox, gordon-tayior and couchman equations for the binary mixtures of dmwps, where the interaction parameter chi was approximately zero. however, for the blends ppo/dmwps (chi < 0), with an increase of molecular weight of ps, it was shown that the experimental results fitted well with those obtained from the couchman, gordon-taylor and fox equations, respectively. furthermore, the gordon-taylor equation was nearly identical to the lu-weiss equation when \chi\ was not very large. further, the dependence of the change of heat capacity associated with the glass transition (delta c-p) on the molecular weight of ps was investigated and an empirical equation was presented.
