✦ Synopsis

The blends of polyethersulfone and phenoxy were prepared by melt mixing in a Brabenderlike apparatus. The specimens for measurements were made by compression molding and then were water-quenched at room temperature under pressure. The tensile strength, tensile modulus, elongation at break and yield, density, thermal analysis, and dynamic mechanical properties were each measured. The dependence of tensile strength, tensile modulus, elongation at break and yield, and density on composition was obtained. The relationship between tensile modulus and elongation at break and yield and speed of the crosshead at different weight ratios of the blends is shown. The effects of composition and miscibility on the mechanical properties are discussed.

The dynamic and tensile properties of Brabender mixed, compressionmolded miscible, and unreacted polyhydroxy ether of bisphenol A (Ph)/Hytrel blends were studied. Blending mainly produced a decrease in the specific volume, and in the strength of the ␀ transition of Ph. The ␀ transition strength decr

A sulfonated polystyrene (SPS) and a polyurethane containing a tertiary amine group (NPU) were blended in solution. The effect of blend composition was studied in the blend of SPS with 9.83 mol % of sulfonation (SPS-9.83) and NPU with 33 mol % of MDEA (NPU-33). As the SPS concentration increases, a

Polyhydroxy ether of bisphenol A (phenoxy)/Hytrel (Hy) blends were obtained by melt mixing throughout the composition range and at several processing times. Interchange reactions took place and were followed by the torque behavior, solubility tests, and FTIR spectra. After a mixing time of 15 min, t

Changes in mechanical properties during isothermal physical aging were investigated for three miscible blends: polystyrene ( PS ) / poly ( 2,6-dimethyl 1,4-phenylene oxide ) ( PPO ) , PS / poly ( vinylmethylether ) ( PVME ) , and poly ( methylmethacrylate ) ( PMMA ) / poly ( ethyleneoxide ) ( PEO )
