    Notes: Summary Weight fraction activity coefficients (Ω1)∞ and interaction parameters x have been determined for seven different solvents in Polyarylate at three temperatures by the gas chromatographic method (inverse gas chromatography). Data have been used to calculate infinite dilution solubility parameters according to the method proposed by DiPaola-Baranyi and Guillet. The validity of the plots involved in the above mentioned method is also discussed.

    Notes: Abstract A study has been carried out on the sorption of ortho-dichlorobenzene, N,N-dimethylformamide and water by poly(ether ether ketone) (PEEK). Two types of PEEK samples have been analysed; the first in the amorphous state and the second with a high crystallinity level. The sorption and desorption curves have been determined and the effect of the solvent presence on the mechanical properties has been analysed by means of the tensile test. PEEK is affected to a different extent by the solvents studied and also by the crystallinity of the polymer. Sorption takes place only in the case of amorphous PEEK. Its effect on the mechanical properties of PEEK is explained on the basis of the two concomitant processes that are the consequence of sorption, these are: plasticization and induced crystallization.

    Notes: Abstract The thermal decomposition of miscible blends composed by the poly(hydroxy ether of bis-phenol A) (phenoxy) and poly(ethylene oxide) (PEO) has been investigated by dynamic thermogravimetric analysis. The results obtained indicate that the blend composition affects the thermal decomposition processes. In general it can be seen that phenoxy causes a negative effect on the thermal stability of the blends.

    Notes: Abstract The phase behaviour and the mechanical properties of binary blends composed of poly(ether ether ketone) and poly(ether sulphone) have been studied both in the amorphous state and after crystallization of poly(ether ether ketone). Differential scanning calorimetry and dynamical mechanical analysis clearly show the existence of phase separation in the blends. Density measurements confirm the absence of strong interactions between the blend components, as well as the slight effect of PES on the crystallization of PEEK. The mechanical properties of the quenched, amorphous blends remain surprisingly good in spite of the observed immiscibility, however, slowly cooled, crystalline blends appear as brittle materials.

    Notes: Summary Glass transition temperatures of different Polyarylate/plasticizer systems with plasticizer concentrations limited to 30 wt.% have been determined by Differential Scanning Calorimetry. Experimental results have been compared to the predictions of three different expressions: the logarithmic rule of mixtures, the Fox equation and the Couchman-Karasz equation. The degree of homogeneity of the different systems has been related to the width of the simple Tg. The data for the different PAr/plasticizer mixtures seem to fit the Fox equation more closely than the other equations tested.

    Notes: Summary A calorimetric study has been done of the miscibility of blends composed of polyarylate (PAr) and poly(ε-caprolactam) (polyamide 6, nylon 6). The thermal transitions of blends subjected to two different thermal treatments have been determined. Two glass transitions have been observed in the blends irrespective of the thermal history. These glass transitions indicate the existence of two amorphous phases in the blends, a practically pure nylon phase and a mixed PAr/nylon 6 phase. The variation of the melting temperature of nylon with the blend composition is in good agreement with the existence of phase separation in the blends. However, the melting heat shows a slightly positive deviation from linearity when it is represented against the blend composition.

    Notes: Summary The crystallization and melting behaviour of poly(butylene terephthalate) has been studied in the pure state and in its blends with a polyarylate of bisphenol A and isophthalic/terephthalic acids. Differential scanning calorimetry has been used as experimental technique and the effects of different thermal treatments have been analyzed. Results show the hindrance for the crystallization of poly(butylene terephthalate) imposed by the presence of polyarylate, as well as the existence of multiple melting after isothermal crystallization. Explanations are given for the observed behaviours.

    Notes: Abstract The combined influence of miscibility and interchange reactions on the thermal and mechanical properties of 50/50 blends of poly(butylene terephthalate) (PBT) and phenoxy, and the nature of the reactions, have been studied. It has been proved by means of Fourier transform infrared spectroscopy and solubility tests that the reaction occurs through the hydroxyl of the phenoxy. Evidence is presented for the additivity of the beneficial effects of miscibility and interchange reactions on the mechanical properties of the quenched, not-fully-crystalline material.

    Notes: Abstract The phase structure and mechanical properties of blends composed of poly(ether imide) and a thermotropic liquid-crystalline copolyester, Rodrun LC-5000, processed by injection molding were studied in the PEI-rich region. The addition of Rodrun to PEI produces fully immiscible blends and strongly improves the processability of PEI. Injection molding gave rise in very poor LCP blends to fine dispersed phases; in the rest of compositions it gave rise to coarse structures. This was probably due to the very large viscosity difference between the components of the blends. An increase in the melt temperature led to a smaller viscosity difference and as a consequence dispersed phase dispersion improved. The Young's modulus clearly increased with the Rodrun content. The tensile strength was maintained up to a LCP content of 5% but decreased at higher contents because of the coarse morphologies obtained. The overall mechanical behavior was a main consequence of the lack of fibrillation and of the LCP dispersion level in the matrix.
