## Abstract The miscibility of blends of phenoxy polymer 1 from bisphenol A and epichlorohydrin and polyacrylates is studied using differential scanning calorimetry (DSC) and Fouriertransform infrared (FTIR) spectroscopy. The DSC curves show that poly(alkyl acrylate)s are immiscible with phenoxy. I
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,
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
