Abstract: LLDPE-g-MAH graft copolymer was used in this paper as compatibilizer to promote the
compatibility of nylon 6 with polyethylene and improve the properties of the blend. The results of mechanical
properties test showed that the addition of compatibilizer significantly improved the properties of the blend.
Among them, the effect of adding A compatibilizer was the best. Compared with the pure blend, the impact
toughness was improved by more than two times, and the nominal strain was also improved significantly;
when the ratio of LLDPE/PA6 was 20/80, the comprehensive effect of mechanical properties was the best,
and the impact toughness increased by 1.1 times; with the increasing of the amount of compatibilizer, the
impact toughness increased continuously. When 15 phr of compatibilizer was used, the impact toughness
was 2.68 times as much as that of the blend without compatibilizers. DSC analysis of the blends showed that
the crystallization peak temperature of nylon 6 and polyethylene increased and the crystallinity decreased
significantly. The addition of compatibilizer increased the crystallinity of polyethylene and decreased the
crystallinity of nylon 6. The crystallinity of nylon 6 increased with the increasing of compatibilizer content, and
the crystallinity of polyethylene decreased. The crystallinity of polyethylene increased and that of nylon 6
decreased with the increasing of polyethylene content in blending ratio. The electron microscopic analysis
of the blends showed that the addition of compatibilizer made the particles of dispersed phase smaller and
more uniform, and compatibilizer played a compatibilizing role in the blends. At the same time, LLDPE-g-MAH
was proved to be an effective compatibilizer.
Key words: graft modification; impact toughness; crystallinity; compatibility; blend modification
