Abstract
The functionalized masterbatch of montmorillonite (FMMT) was prepared when monomer acrylic amide (AM), organic-MMT (OMMT) and initiator dibenzoyl peroxide (BPO) were added to acrylonitrile-butadiene-styrene (ABS) carrier which has been dissolved by 1,2-dichloroethane. The influences of AM and BPO amount, reaction time, and reaction temperature on grafting degree were investigated by the orthogonal experimental design. The range analysis showed that optimal conditions for preparing FMMT are AM (1.6 g), BPO (0.4 g), reaction temperature 90°C and reaction time 2 h. The structure of FMMT was characterized by the test of infrared (IR), x-ray diffraction (XRD) and transmission electron microscope (TEM). The results confirmed that AM was successfully grafted onto ABS, the masterbatch was a kind of intercalculated nanocomposite and the gallery height of nanocomposite was 3.42 nm. When montmorillonite was blended with ABS in the form of masterbatch, ABS/FMMT composite was a kind of exfoliated nanocomposite compared to the ABS/Montmorillonite (MMT), ABS/OMMT composites.
