摘要：

The analysis of some dielectric properties of poly-(ether block amide) PEBAX having a hard-segment polyamide 12 ( OVER BAR M//n equals 4200) and soft-segment polytetramethylene glycol ( OVER BAR M//n equals 2032) has been done by a thermally stimulated depolarisation current method. The relaxation peaks resulting from molecular motions are similar to those observed in pure homopolymers. The mechanical properties of PEBAX depend primarily on the hard-segment contents. The domain morphology is affected by thermal treatment. The existence of separate glass transition peaks representative of PTMG and PA 12 in PEBAX has been confirmed by a compensation law.
