Rheological and Crystallization Properties of ABS/PA6-CompatibilizedBlends via In Situ Reactive Extrusion
2020
ABS/PA6-compatibilized blends were
prepared by in situ reactive
extrusion method. The main objective was to evaluate the influences
of the morphology and blend composition on the rheological and nonisothermal
crystallization properties. The morphology of submicron-sized ABS
droplets evenly dispersed in PA6 led to dilatant fluid behavior and
a transition from elastic to viscous behavior in the low-frequency
region. The crystallization results indicated that reactive blends
had elevated crystallization temperatures and crystallization rates,
which were due to the heterogeneous nucleation of the submicron-sized
ABS particles. In addition, it was observed that the theory by Mo
suitably described the nonisothermal crystallization process. The
activation energy slightly decreased for ABS contents of 5 and 15
wt % and then increased for a content of 25 wt %, indicating that
the ABS promoted the crystallization of the blends at appropriate
contents.
