COMPATIBILIZATION OF ABS/PA6 BLENDS USING OLEFIN BASED POLYMERS

摘要

This study focuses on the morphologies, mechanical and thermal properties of poly(acrylonitrile-co-styrene-graft-butadiene)/polyamide-6 (ABS/PA6) blends compatibilized with methyl acrylate and glycidyl methacrylate grafted polyethylene (E-MA-GMA) and n-butyl acrylate and maleic anhydride grafted, carbon monoxide modified polyethylene (E-nBA-MAH). The ABS/PA6 ratio (100:0, 80:20, 50:50, 20:80 and 0:100) and compatibilizer content (0, 5 and 10%) are examined as the experimental variables. Compatibilization improves impact strength of the blends. Super-tough blends were obtained at definite compositions (ABS/PA6/E-nBA-MAH: 50/50/5, ABS/PA6/E-MA-GMA: 50/50/5). Dispersed domain size became remarkably smaller for compatibilized blends compared to incompatibilized ones. It was concluded that olefin based copolymers are potential compatibilizers for ABS/PA6 blends.
