Tensile stress-strain characteristics : module of elasticity (E), stress at break ( sB) and elongation at break (eB) of POM blends at different EOK , TPU, ABS or EVA weight contents. POM has been modified with ethylene vinyl acetate copolymers with various vinyl group contents- 30% (EVA30) and 21% (EVA21); ethylene α-octene copolymers with various α-octene contents- 38 % (EOK38) and 17% (EOK17); thermoplastic polyurethane (TPU) and acrylonitrile-butadiene elastomer (ABS).
