摘要

Methyl acrylate/acrylonitrile copolymers (MA/AN) were reactively compatibilized as the dispersed phase into poly(ethylene) (PE) for potential hydrocarbon barrier materials. The MA/AN was made reactive by including p-aminostyrene (PAS), yielding terpolymers (MA/AN/PAS) with pendant primary amine functionality (number average molecular weight M-n = 65-133 kg mol(-1), dispersity (D) 51.83-2.53, molar composition of PAS in copolymer F-PAS = 0.03-0.14, molar composition of AN5FAN50.27-0.52). The non-functional MA/AN and amino functional MA/AN/PAS were each melt blended into PE that was grafted with maleic anhydride (PE-g-MAnn) at 200 degrees C at 70: 30 wt % PE-g-MAnn: co/terpolymer. After extrusion, the dispersed phase particle size (volume to surface area diameter, (< D >(vs)) was coarse (12.6 mu m) for the non-reactive blend whereas it was much lower for the reactive blend (< D >(vs) 5 1.2 mu m). Coarsening after annealing at 150 degrees C was slow, but the domain sizes increased only slightly for both cases. The reactive blend was deemed sufficiently stable and thus was suitable as a candidate barrier material for further testing against olefins. (C) 2016 Wiley Periodicals, Inc.
