| Abstract: | Butadiene-acrylonitrile rubber/organomodified bentonite (NBR/OMB) intercalated hybrids were prepared with latex intercalation technique. The mechanical properties and microstructure of NBR/OMB were investigated. The results showed that the organomodified bentonite is an effective toughening modifier for NBR. The results of transimission electronic microscopy (TEM) and X-ray diffraction (XRD) showed that the NBR macromolecule could be intercalated in the interlayer of bentonite. NBR/OMB hybrids was used as toughening modifier for Poly(vinyl chloride) (PVC). The results showed that incorporation of NBR/OMB hybrids into PVC leads to substantial increase in impact strength with retention in tensile strength and flexible strength compared to the unmodified PVC. |
