Abstract

Abstract: A series of polycaprolactam(PA6)/poly(ether sulfone)(PES) blends were prepared in a Brabender-like apparatus and the effect of PES on crystallization and melting behavior of PA6 has been investigated by DSC technique. The melting temperature and nonisothermal crystallization temperature of PA6 decreased with increase of weight fraction of PES in blends. Three melting peaks were found in DSC isothermogram. The Avrami exponents varied between 3.2 and 3.7, almost irrespertive of T_c and composition, and the rate of crystallization decresed with increase of temperature and PES content.

Key words: polycaprolactam, poly(ether sulfone), blend, crystallization, melting property
