Abstract
The influences of organoclay on properties of chlorosulfonated polyethylene (CSPE) are scrutinized by loading different filler amounts to the polymeric matrix. In addition, cure characteristics of the prepared nanocomposites are determined by using rheometeric analysis. Although maximum and minimum torque values illustrate a slight increase with the organoclay incorporation, both scorch time and cure time of nanocomposites present a reduction in the presence of organoclay. The tensile strength and elongation at break of nanocomposites went through a maximum as a function of the organoclay content. As expected, the hardness, moduli at 100% and 300% elongations continuously increased along with increasing organoclay loading. The dispersion of organoclay in CSPE chaning was analyzed by X‐ray diffraction and FESEM, methods. The best clay dispersion was achieved at 6 phr lauding by adding ENR 50. This was also observed in the stiffness of nanocomposites derived from both dynamic mechanical thermal analysis (DMTA) and tensile tests. J. VINYL ADDIT.
