Abstract

We propose a new method for the preparation of the polymer/organoclay nanocomposite, termed the solution and melt mixing (SOAM) method, where the polymer and clays are first blended in solution, and subsequently the mixture is further blended in the melt. We prepared the ternary nanocomposite systems of poly(styrene-co-acrylonitrile) (SAN), poly(vinyl chloride) (PVC) and Cloisite25A clays (C25A) by solution blending as well as by the SOAM method. The C25A content in the nanocomposite was optimized by analyzing the x-ray diffraction (XRD) data of binary mixtures (SAN/C25A and PVC/C25A nanocomposites). The values of the interaction parameter (χab) were calculated by using the molar attraction constants of the specific functional groups derived from Hoy’s table. While PVC and C25A were shown to be highly compatible, SAN and C25A were less compatible. XRD data and transmission electron microscopy observations indicated that the SAN/PVC/C25A nanocomposites had at least partially exfoliated structures. The tensile modulus and the elongation at break of the nanocomposites prepared by the SOAM method were higher than those prepared by simple solution blending.
