Title Influence of layered double hydroxides on the curing of carboxylated nitrile rubber with zinc oxide
Date 14.09.2009
Number 20962
Abstract Unmodified (LDH) and modified (mLDH) layered double hydroxides have been added to gum and ZnO-cured carboxylated nitrile rubber (XNBR). It was observed that both LDH and mLDH inhibit the formation of ionic cross-links between XNBR and ZnO quite significantly, as is evident from DMA and FT-IR studies. The suppression of ionic cross-links formation was also reflected in the mechanical properties of the resulting composites. A tentative sketch has also been suggested for the possible mechanism involved in the inhibition of ionic cross-links by LDHs. X-ray diffraction and STEM studies were performed to see the dispersion of LDH's in the elastomer matrix.
