| 中文摘要 | the miscibility of blends of cellulose diacetate (cda) and poly(vinyl pyrrolidone) (pvp) was extensively studied by means of differential thermal analysis and dynamic mechanical thermal analysis, tensile test, measuring viscosity of diluted and concentrated solutions of blends in acetone-ethanol mixture and morphological observations. a single glass transition temperature is observed, which is intermediate between the glass transition temperatures associated with each component and depends on composition. a synergism in mechanical properties of blends was found. the absolute viscosity and the intrinsic viscosity of solutions of blends are much higher than the weight average values of solutions of cda and pvp. optically clear and thermodynamically stable films were formed in the composition range of cda/pvp = 100/0 to 50/50w/w. fourier transform infrared was used to investigate the nature of cda-pvp interaction. hydrogen bonds were formed between hydroxyl groups of cda and carbonyl groups of pvp. heats of solutions of cda/pvp blends and their mechanical mixtures were measured by using a calorimeter. mixing enthalpy obtained with hess's law approach was used to quantify interaction parameters of this blending system. it was found that mixing enthalpies and interaction parameters were negative and composition dependent.
