Abstract

Reactive blending of polyamide 6 (PA) with polyethylene (PE) having reactive sites, maleic anhydride (MAH content= 0.1 wt%),and glycidyl methacrylate(GMA content = 3-12 wt%), was carried out at 70/30 and 65/35 (PA/PE) blendratios. Blend morphology evolved by reactive blending was analyzed by light scattering and transmission electron microscopy. The blends were then irradiated by electron beam. The degree of crosslinking was estimated by measuring the dynamic storage modulus at a temperature above melting point of PA. It was found that surface-to-surface interparticle distance tau was significantly reduced by the micelle formation via pull-out of in situ-formed graft copolymers. The blend with shorter tau was crosslinked by electron-beamirradiation at the lower dose level. A blend having the minimum tau (similar to0.2 mum) was nicely crosslinked at a low dose level same as for PE, and even for the PA matrix system. (C) 2001 Elsevier Science Ltd. All rights reserved.
