Poly(ether‐block‐amide) (PEBA) were prepared by means of a condensation reaction with polyamide‐6 as hard segment and polyether as soft segment. The optimal reaction conditions were determined as the followings: 3% of water and 0.35% of catalyst, reaction temperature 260°C ± 5°C and the reaction time 4 h under the N 2 atmosphere, and 1 h under the vacuum, the vacuum <80 Pa. Characterization results of FTIR and 1 H‐NMR showed that the block copolymer of polyether and polyamide was synthesized successfully. The obtained PEBA was applied as an antistatic agent for the ABS resin. The research results showed that the blend with the best properties was PEBA2‐2/ABS and the dosage of PEBA was 12%. PEBA2‐2 could obviously decrease the surface resistivity of ABS from 10 14 to 10 10 Ω and also exhibit good persistent antistatic ability. The surface resistivity of the blends decreased with the increase of content of PEBA. The increase of ratio of polyether in PEBA was favorable for the decrease of surface resistivity of the blends. The observation of SEM indicated that the PEBA and ABS had good compatibility. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
