Polyblends of three engineering thermoplastics with three engineering thermoplastic elastomers and three compatibilizers produced four examples of synergistic improvement of impact strength and, in one case, surprisingly, increase of modulus. Blending 10% of polyetheramide with polysulfone increased impact strength up to 5×. Blending 10% of polyurethane with polysulfone increased impact strength up to 4×. Blending 10% of polyetheramide plus 1–5% of phenoxy resin with polyarylate increased impact strength up to 2×. Blending 25% of polyetherester plus 2–4% of compatibilizers (phenoxy resin, polybutylene terephthalate, or styrene/maleic anhydride) with polyarylate surprisingly increased tensile modulus up to 31%. Blending 10% of polyetherester with polybutylene terephthalate increased impact strength 58%.
